Reflections on the Hadrian’s Wall Pilgrimage 2019

“There are things we know that we know. There are known unknowns. That is to say there are things that we now know we don’t know. But there are also unknown unknowns. There are things we do not know we don’t know.”

On our final coach journey of the Pilgrimage, this (at the time much derided) quote from Donald Rumsfeld was used to sum up the current state of knowledge about Hadrian’s Wall. We certainly left with more unanswered questions than we had started with – and maybe this was the objective of our excellent guides?

The Pilgrimage was enjoyable, entertaining and educational – and also very good exercise, especially the final steep climb to Mucklebank Turret (T44b). Our heartfelt thanks go to the Chief Pilgrim, David Breeze, and to everyone else who made this Pilgrimage possible. 

Here are 3 of the many questions and new ideas to us that stuck in our memories afterwards:
– could the reputed ‘white washing’ of the Wall in fact be the by-product of brush pointing using water with a lime wash in finishing construction?
– when the Turf Wall had recently been constructed in the West, it would have looked quite extraordinary as a green turf strip, with stone watchtowers, striding through a landscape of exposed pink and white clay soil, and 
– spreading out the 2nd Century Roman Field Army in forts dispersed across north of England and southern Scotland would have solved much of the logistical problem faced by such a vast force: when an army is concentrated it soon runs out of food and pollutes the water supply, thus it has to keep moving. So, whatever the other motives, parking units across the landscape made logistical sense.

The Vallum west of Carrawburgh

Here are three controversies we enjoyed hearing kicked about:
– were there a wall walk and crenellations on top of Hadrian’s Wall?  Almost all reconstructions assume so, but is there actually any firm evidence either way?
– what was the Vallum for? At the misnamed Limestone Corner, the extreme hardness of the local dolerite stone finally caused the legionaries to give up on digging the ditch in front of the Wall but it did not stop the (presumed) auxiliaries digging the Vallum.  So the Vallum clearly mattered – but was it there to stop cattle rustling, as a second line of defence, to create a cattle and horse compound, as a border control device, as a road to move troops or as the boundary of the civil province? (Maybe it fulfilled most of these functions at some times and on some stretches…)
– did Hadrian order the construction of ‘his’ Wall before he visited Britannia or when he arrived and had inspected the British challenge? Indeed, could Hadrian himself have made the Decision to move the Forts forward from the earlier Stanegate to the line of the Wall itself (the ‘Forts Decision’)?

Chesters Baths, by the River North Tyne

Finally (and very subjectively and unscientifically), our favourites from all the many things we saw were:

Best Fort

Chesters because of its situation, and its Principia and Baths.

Chesters very traditional Museum

Best Museum

Chesters again, not just because of the wonderful contents, but because it has ‘a museum of a museum’ with proper descriptions, find sites and accession numbers. 

Mucklebank turret – note window arches where they fell!

Best Turret

Mucklebank, because it has the original unconsolidated stonework and forms a stunning right angle over a precipitous drop! Also, an ‘Honourable Mention’ for Banks East (T52a) because it was built to be part of the earlier Turf Wall (although EH don’t depict it that way).

Poltross Burn MC 48 – note 3 steps of stairs leading up…

Best Milecastle

Poltross Burn, aka the King’s Stables (MC48), near Gilsland, with surviving bases of two substantial internal stone buildings and, crucially, three steps that must have led up to a higher level…

East rampart of Burnhead temporary camp

Best Camp

Burnhead, near Cawfields – the only camp we visited but a first for the Pilgrimage and with so much more to learn.

The 4th Century Commanders House

Best Reconstruction

South Shields 2nd Century grand West Gate, 3rd Century squalid Barracks and 4th Century luxury Commander’s Mansion. 

Replica Auxiliary Cavalryman in the Roman Army Museum, Carvoran

Best Use of Tech

The Roman Army Museum at Carvoran. Here (unlike most museums which try too hard to be ‘cool’ and/or have broken display screens and installations), the interactives (the 3D eagle film, the fearsome Commander of Auxiliaries, and the squadies arguing and having bloody leg surgery) are all high-quality and engaging productions.

Pike Hill Turret, Hadrian’s Wall

Overall Impact.     * 1 star.  Not much to see but this turret of great interest to students of the Wall since it’s a survival of the earlier Stanegate Frontier, subsequently incorporated into Hadrian’s Wall. 

Access.     ** 2 star.   Park in the car park for Banks East (Turret 52a) and walk for 100m up the hill to Pike Hill Turret. 

Atmosphere       **  2 stars.   There’s only about one third of the lower courses of the original Turret remaining after C19th and C20th road building.  You need to use your imagination to work out what the original would have looked like.

Other.     ** 2 stars.   If you look southwards, you see a magnificent panorama across the southern fells. 

Pike Hill Turret was designed as a forward lookout in the years before the Wall itself was constructed. 

Pike Hill Turret remains looking North.

In the reign of Trajan (Hadrian’s predecessor) the Stanegate was the frontier of the Roman Province.  Forts on the Stanegate situated in the valleys of the River Irthing and the River Tyne needed ‘eyes’ up the northern slope – hence the construction of this small forward lookout with wide views from which troops could communicate with the Stanegate fort at Nether Denton.

Wide view to the South from Pike Hill Turret

Once Hadrian’s Wall was being constructed Pike Hill Turret was subsumed in the wall line (but not allowed to interfere with the new “milecastle and turret” scheme). Presumably it stayed in use and could now also communicate along the Wall.

Housesteads Roman Fort

Overall Impact **** 4 stars – Housesteads has ‘star quality’, given its position atop the crags and on a slope that faces you as you approach.

Access ** 2 stars – it’s a long trudge up from the National Trust carpark, although it provides spectacular views of the fort in its context (although disabled parking at the top of the hill can be arranged at the information centre for those who require it). It can be windy and uneven underfoot.

Atmosphere ***** 5 stars – it’s not difficult to imagine you are a one of the Tungrian soldiers stationed there, gazing out into the drizzle to spot raiders or smugglers!

Other ** 2 stars – the famous latrine provides a good source of lavatorial humour for children of all ages!

For many people, Housesteads is the quintessential Roman auxiliary fort and it is definitely ‘the fort to see’ on Hadrian’s Wall. However, as always, when you dig into things with the Roman Army, it’s not quite that simple…

Housesteads was one of the forts built as a result of the ‘Fort Decision’ in around AD124 when the Roman High Command decided that – instead of a thinly-held ‘curtain’ along the new frontier with turrets and milecastles communicating with forts in the rear along the Stanegate Road – it was necessary to man the border with troops of all kinds, ready to be deployed forward aggressively. At the same time, probably, the decision was taken to narrow the wall from a massive 10ft to 6ft. Wall expert David Breeze estimates that troops on the front line increased from c3,750 to c11,000.

Panorama views looking north from the wall of Housesteads Fort

Part of that deployment was the deployment of a thousand-strong infantry cohort (Cohors Peditata Milliaria) to Housesteads. This involved the knocking down of a part-constructed turret which can be seen in the northern part of the fort, outside the granaries and just inside the fort wall which was then pushed as far towards the edge of the cliffs as possible, making the North Gate meaningless and purely decorative. But they still built it – after all, this is the Roman Army!

English Heritage have provided excellent reconstructions to bring the site to life.

Since it contained 10 centuries of 80 men each (800 in total), the fort is larger than normal at 2.2 hectares. There were 10 infantry barrack blocks: 5 west of the central range and 5 east, each row containing an additional workshop building. In the central range, stood the usual HQ (Principia), this time facing east along the long axis, with two substantial granaries to the north, and a magnificent house (Praetorium) for the Commander and his family, with a Hospital behind. All of these were built on a steeply sloping site, exposed to the frequent wind and rain of the Northumberland weather. So the ‘poor bloody infantry’ got Housesteads Crags, whilst the better-paid elite cavalry got the bucolic pleasures of Chesters in the North Tyne Valley.

The twin Granaries from the original Hadrianic fort, subsequently modified and knocked together.

We don’t know which unit was lucky enough to get this windy posting: clearly being ready at short notice to deploy aggressively north of the Wall was vital – why else put them here? However, along with the rest of the Wall, all this site was dismantled or moth-balled after Hadrian’s death in AD138, and Antoninus Pius’ decision to move the frontier forward to the Clyde-Forth Isthmus and to what become the Antonine Wall. So could we look on the 50 years of Hadrian, Antoninus Pius, Marcus Aurelius and Lucius Verus from AD117 to 167 – far from being the Golden Age of the Roman Army – as being instead an era at least of indecision and waste of effort, or even of failure?

When the Army came back to the Wall in the early AD160s, the Housesterads garrison was the Cohors I Tungrorum which by now had a complement of 800 infantry. Originally recruited as auxiliaries from the native Tungri of Belgica, they had been stationed at Vindolanda in the late 1st Century, and by the AD180s would have become thoroughly local on the Wall. They were augmented by barbarian irregular infantry from ‘free’ Germany (Numerus Hnaudfridi) and cavalry from Frisia (Cuneus Frisiorum), presumably recruited to provide a certain ‘barbaric’ edge to the Tungrians’ regular tactics.

Amazingly, the Tungrians were still there at Housesteads by the time of the Notitia Dignitatum in the late 4th Century. However, by then the neat barrack blocks had been divided up into what have been somewhat weirdly named ‘chalets’, one replacing each previous set of contubernia rooms. Some people think this reflects the decline of the Roman Army, with families moving into the ‘chalets’ along with the soldiers. But at Housesteads there is very little evidence for this happening (unlike at Vindolanda), so the reason for the rebuild remains unclear.

Visiting the Site

You stand a good chance at Housesteads of being blown away, drenched or at best slightly dampened by the Gods of the Northumbrian Weather. However, there is plenty exposed on the site from different periods which is well worth seeing.

Rather excellent model of Housesteads Fort as built.

The best plan is to visit the Museum (housed in the old farm buildings) on your way onto the site. Here are some key finds from the fort plus a really good model of the fort as it was built in the AD120s and some excellent pictorial reconstructions of the whole fort and its key buildings. What is most striking is how the Roman architects did not let the sloping nature of the site get in the way of laying out the regulation plan; and how much effort was put into constructing a multi-storey Commander’s House with a central courtyard – great in the Mediterranean but probably a source of flooding up here.

Badge of Office – possibly of a Beneficarius Consularis an official on the Governor’s Staff – in the Housesteads Museum

It is worth then visiting the (pointless) North Gate to look over into the Barbarian lands and a view for miles north, and to gaze west and east along the Wall that bestrides the crags. And in the north-east quadrant you can see the ‘chalets’ laid out in their irregular plans.

As a final treat, everyone visits the south-east corner to marvel at the Roman latrines, which were flushed by the plentiful rainfall at Housesteads. Apparently, though, the plumbing is not so clever and effective as it looks…

South Shields Roman Fort

Overall Impact **** 4 stars – One of the most unusual Roman forts to be found in Britain. Started off quite normal but then became the supply base for Septimius Severus’ campaigns in Scotland and thereafter for the garrison of Hadrian’s Wall – unique!

Access *** 3 stars – One of Tyne and Wear Museum Service flagship sites, Arbeia is well branded and signed. There is parking outside plus extensive beach-side car parks. (It takes some time to drive to South Shields from Newcastle, however, either through the Tyne Tunnel or by heading south down the A1 and then back up.)

Atmosphere ***** 5 stars – The Fort feels special: it has been a “People’s Roman Park” since the 1870s when the central area was exposed, and the 3 amazing reconstructions (the West Gate from AD160s, 3rd century barracks and 4th century Commander’s House) are very evocative.

Other **** 4 stars – Don’t miss the two high-quality tombstones of Regina and Victor probably carved by a Syrian craftsman in the small Museum. (The Bookshop sadly did not, however, seem to include a current Guidebook to the site when we were there.)

The tombstones of Regina (on the left) and Victor (right).

One of the most unusual forts – well worth making the effort to visit, in the Hadrian’s Wall Region or Complex but definitely not ‘on the Wall’, is South Shields or ‘Arbeia’ as it is branded at the site and on signposts.

The brightly painted Courtyard of the Commander’s House from the 4th Century.

It was built as part of the Antonine re-occupation of the Tyne-Solway line in the early 160s and is a ‘bog standard’ auxiliary fort for a Cohors Equitata Quingenaria). In the middle range stands the Headquarters (Principia), facing north, with a pair of granaries to the west and the Commander’s House (Praetorium) to the east. In front of them there appear to be 6 barrack blocks (6 x 80 men = 480 infantry) and behind there are 4 cavalry barracks with urine pits for the horses in the front rooms of the conturbernia (4 x 30 = 120 troopers), housing a total of 600 troops. It feels like the twin of Wallsend built in the late AD130s and reoccupied at the same time as South Shields in the AD160s.

South Shields gets really interesting in AD207 when the fort is converted into a supply base for Septimius Severus’ campaigns in Caledonia. The fort is extended to the south and a dividing wall erected across the middle. The old Principia is demolished and a new smaller one, now facing south, is built. The barracks are removed and an amazing 13 new granaries are built which, with the two existing ones, gives 15. The poor old garrison unit Cohors V Gallorum is therefore jammed into the southern half of the site in shortened barrack blocks.

The exceptionally large Strongroom in the Principia – the largest in Britain – presumably for storing the pay chests arriving for the Wall garrisons.

This scheme is never finished and the dividing wall is knocked down, still more granaries built, bringing the total to 22, and some more barracks are crammed into the south-east corner.

South Shields continued as a Supply Base for the Army on Hadrian’s Wall after the departure of Septimius Severus and his son (and fellow Augustus) Caracalla. Another new Principia was built and some short barracks replaced the previous ones. This role continued during the 3rd Century with grain imported from northern Gaul. Interestingly in the Notitia Dignitatum from the late 4th Century the garrison is a unit of Tigris Boatmen or Bargemen from present-day Iraq). It is an attractive theory to see these troops arriving with Septimius to transport grain and supplies up the coast to the Army in the north and staying to distribute supplies up the Tyne to the Wall garrison afterwards. Severus had previously been campaigning in the East and had created the new Province of Mesopotamia with its frontier on the Tigris. The name Arbeia is thought to be a version of ‘Arabia’ relating to this deployment. The freedwoman Regina, whose tombstone was found in the civilian settlement (vicus) here, was the wife of Barates from Palymra. Barates himself is thought to be buried at Corbridge (Coria) behind the Wall.

A disastrous fire around AD300 destroyed the fort, cause unknown. In the resultant rebuilding, eight of the granaries in the south were converted into barrack blocks, each with space for 5 conturbernia (5 x 8 men = 40), housing a total of around 320 men. The Commanding Officer of this unit – and this may be when the Tigris Bargemen were in fact deployed here – had a large, even palatial, Praetorium complete with integral bath suite and both summer and winter dining rooms. Arbeia seems to have functioned as the supply base for the Wall through the 4th Century until the breakdown of the imperial pay- and supply-chains in the early 5th century. It may well have become a centre of royal Northumbrian power thereafter.

Reconstructions

So, for everyone interested in Roman forts, this complex evolution is ridiculously interesting. And now you can add to that the three – yes, three – unique reconstructions that Paul Bidwell and the Tyne and Wear Museums Team have built.

Fort Gateway

The reconstructed West Gate leading to the presumed docks, originally built c160AD.

The West Gateway has been reconstructed on its foundations to its full imposing height, something which is quite common along the German Limes but scarcely ever happens in Britain. Opened in 1988, faithfully reflecting the stone fragments found on site and using Northumbrian stone externally, it brings home to visitors and school parties just how imposing a Roman fort was in the landscape. The new version has weathered its 30 years in the Tyneside climate very well.

Barrack Block

The reconstructed barrack block is one of the new types of the 3rd Century with 5 contubernia plus officers’ quarters at one end. Unlike the robust Gate, the barracks building brings home to modern eyes what a rotten, cold and often soaking wet life a Roman auxiliary led. It is built of clay-bonded stone and mud plaster coated with limewash, with internal partitions of wattle and daub. If the unit was up to strength then these rooms would have been crowded with up to 8 men and all their kit, and smoke-filled from cooking and heating. The reproductions – probably like the originals – are not surviving well in the Tyneside weather, with plaster flaking off.

A crowded rear room in one of the conturbernia.

Commander’s House from the 4th Century

Next door to the crumbling barracks is a recreation (on the original foundations) of the unique Commander’s House from the 4th Century. It is decorated with tremendous panache and joie de vivre in bright colours with what to modern eyes look like naive fake painted marble and portraits of the Emperor. This suggests at what you could achieve even in the the far north-west of the Empire with local craftsmen.

The portico leading to the Summer Dining Room.

There are store rooms, the Commander’s study, two bedrooms, a vast summer dining room and a painted courtyard. Yet this still leaves the winter dining room, with extra heating, and the bath suite not reconstructed! Only the top man and his family lived in such luxury…

Commander’s Bedroom.

The Commander’s House is showing some wear and tear, but its impact is still like no other reconstruction we have seen. Interestingly, the reproduction Roman tiles (tegulae et imbrices), manufactured specially in Italy, let in the rain – given how they were first fitted – leading to the collapse of the painted ceiling in the dining room!

Reproductions of Late Roman furniture.

Museum

In the small but good Museum there are two high-quality tombstones probably carved by a Syrian craftsman. They are both rightly famous and provoke so many questions about the nature of society and relationships in Roman Britain. One is to Regina, a freedwoman and the wife of Barates – he was from Palmyra, she was from the Catuvellauni living around St Albans. The second is to Victor who died at 20, a former Moorish slave freed by Numerianus of the Ala I Asturum who arranged his funeral ‘with all devotion’. There is also a good range of other finds from the site.

Chesters Fort

Overall Impact:                **** 4 stars – One of the best ways to get a feel for a ‘standard’ Roman auxiliary fort: you can examine the gates, Principia and baths and understand how they worked.

Access                                ***** 5 stars – As a prime English Heritage Hadrian’s Wall site, it is well signposted from both directions, with the AD122 bus stop plus ample car parking space, and good visitor facilities. Most areas of the site are easily walkable.

Atmosphere                      ** 2 stars – In the absence of anything other than walls and information signs, you need to use your imagination to recreate the fort. But there are good children’s activities which help with that.

Other                                  *** 3 stars – Clayton Museum at the site has been beautifully restored to its nineteenth-century splendour. As a bonus, across the River North Tyne is the surviving bridge abutment.

The ‘Matres’ in an inscription in the Clayton Museum

Chesters (Roman Cilurnum) was one of the forts built on the line of Hadrian’s Wall when the original conception of a wall composed of milecastles and turrets was abandoned and the decision was taken to move forts from the Tyne Valley forward to the line of the Wall itself. Given that the Wall was begun in AD122, Chesters therefore dates from a few years thereafter: English Heritage plump for a date of AD124. The ditch in front of the Wall was filled in and a turret that had just been built (or at least started) on the site was demolished.

Statue of Juno Dolichena, consort of Jupiter Dolichenus, standing on a heifer, wearing Eastern garb – the cult originated in Syria. Statue is in the Clayton Museum and was found at Chexters.

The original Hadrianic garrison was Ala Augusta ob virtutem appellata, that is, the Cavalry Wing or Regiment Awarded the Title Augusta for its Valour. As a cavalry regiment it was one of the most prestigious units on the Wall, and had landed a delightful billet beside the River North Tyne in what was probably, then as now, a fertile and attractive spot. A cavalry ala had 16 squadrons (turmae) of 32 men and their horses.

Probably abandoned or mothballed during the move forward in the Antonine period, by AD178-84 the fort garrison was Ala II Asturum, a cavalry wing originally raised in Northwest Spain who were there throughout the remaining lifetime of the fort into the 4th Century. At this period the buildings inside the fort were completely rebuilt. Interestingly, there seems not to have been space inside the fort for the 16 barracks needed for the 16 Squadrons of an ala: either the Ala II Asturum only had 12, or perhaps the remainder were on detached duties elsewhere in the Province and only rotated through Chesters?

The late 2nd and early 3rd Century were the heyday of Chesters with a large civil settlement (vicus) to the South and many inscriptions raised. However, the nature of the fort would have completely changed over the period AD250 to 350 with the vicus largely disappearing and the civilians moving into the Fort. The garrison would have been drawn from the sons of serving soldiers as was compulsory in the Late Empire. An inscription from AD286 refers to irregular troops (symmacharii) also being present at Chesters.

Principal Visible Remains

Excavations were carried out by landowner John Clayton in the 19th Century, so what we have are the surviving walls plus the inscriptions and sculptures now displayed in the charming Museum. Four Hadrianic gates excavated by Clayton (out of the total of six) are exposed: the original double entrances were not needed, or were too insecure, and one of them was blocked early in all cases. Was this to facilitate security checks on those passing through, or due to a realisation that the ability to deploy horsemen quickly through three double gateways north of the Wall was not in fact needed?

The South Gate with double arches, one comprehensively blocked.

The Hadrianic headquarters building (Principia) is large, as befits an elite Ala, and gives a good impression of what a fort HQ was like, with the vault of the strongroom, opening off the central Shrine of the Standards, still surviving. The layout of the Commander’s House (Praetorium) defeats explanation and will continue to do so, given when and how it was excavated. However, the Commander clearly enjoyed his own bath suite.

The Arch of the Strong Room opening off the Shrine of the Standards in the Principia at Chesters.

Most of the rest of the interior is unexcavated. The key visible remains are the two opposing barrack blocks. Based on comparison with German forts and excavations at Wallsend, these are now seen as two-storey buildings. The current view is that there were 10 contubernia which each housed 3 horses in the front room and their riders in the back room (although we prefer the idea that the men slept upstairs, leaving equipment and possibly grooms in the back room). This would allow for 30 men and riders in a squadron (turma), with their commander (optio) and the Standard Bearer in the larger end rooms.

View of the Baths from up the slope towards the Fort – River North Tyne in the background.

The star surviving remains are the garrison Baths, between the fort and the river. They are Hadrianic but heavily modified They famously have niches (possibly for clothes) in the large changing room, plus a surviving base of a window, stone channels with lead seals still remaining, and a latrine on the riverside. These bath would have been a welcome luxury for the elite soldiers stationed at Chesters.

Tetrarchic Thessaloniki – Galerius’ Palace

Overall Impact:                *** 3 stars – Galerius’ Palace impresses through its scale but, having been incorporated in the medieval and Ottoman city, the Roman remains consist of foundations and walls.

Access                                **** 4 stars – As with the other sites in Thessaloniki the site is well cared for and curated, and is only a short walk southwards from the Arch of Galerius toward the sea.

Atmosphere                      ** 2 stars – You will need to use your imagination to recreate the Roman Palace. It is overshadowed by modern housing, but hats off to the City Fathers for displaying such important remains in an area where space is tight.

Other                                  *** 3 stars – OK, it’s not Diocletian’s Palace at Split, and it’s in a busy city and hard to visualise, BUT it is Galerius’ Palace in Thessaloniki and very much worth seeing!

The above photo shows the remains of Galerius’ Basilica or audience chamber, with the nave to the left in front of us. We should be thinking here in terms of Constantine’s Aula Palatina which survives at Trier.

We can see here – above and below – the remains of the Peristyle Hall, with 11 rooms arranged round a courtyard with a fountain.

Above are the exposed remains of the Apsidal Hall. This was a magnificent part of the Palace between the Arch and the Basilica. It has two rooms and ended in a raised niche: was it a more private and intimate Throne Room? It had rich decoration with white and coloured marble on the walls.

Marvellous reconstruction by the Ephorate of Antiquities of Thessaloniki City, which can be found at galeriuspalace.culture.gr
At bottom was the Rotunda or Mausoleum, then a porticoed way to the Arch of Galerius, and then another portico way lead to the Apsidal Hall, which in turn lead to the Basilica with the Circus to the left (west) and the Palace Complex to the right (east).
Another marvellous Plan by the Ephorate of Antiquities of Thessaloniki City, to be found at galeriuspalace.culture.gr They rightly won European awards for the quality of their restoration and public explanation. The idea of making visible the Late Roman City of Thessaloniki originated with the plans for the Reconstruction of the City after the disastrous fire of 1917.

Tetrarchic Thessaloniki – The Mausoleum of Galerius

Overall Impact:                ***** 5 stars – Less well known than the Arch of Galerius but has the impact of the Pantheon in Rome. A unique survival (and a marvellous surprise to us!)

Access                                **** 4 stars – Situated a short walk (125m) north of the Arch and, unlike the Arch, in a quiet side street. Recently restored and now open to the public.

Atmosphere                      *** 3 stars – C5th mosaics only partially remain. Damaged during the Mausoleum’s period as an Ottoman Mosque, they have now been wonderfully restored.

Other                                  ** 2 stars – There is no good guide book on sale at the site – but do check out local book shops for a scholarly exposition which we happened upon. No good post cards available.

The Rotunda of Galerius is north of his Arch: built in AD306, it is usually thought to have been intended as his Mausoleum. However, when in AD311 Galerius died hideously from a disease usually interpreted as gangrene, he was buried at Felix Romuliana (Gamzigrad in Serbia), his birthplace. Therefore it probably never fulfilled its intended function.

The Rotunda’s dome is 30m high and is one of the largest surviving from the Empire. The walls are extremely thick, explaining how it has survived earthquakes through the centuries.

East End Apse added when Mausoleum converted into Church in late C4th

It was empty until Theodosius I had it converted into a church in the late C4th. It was then decorated with some very fine mosaics apparently depicting prominent members of the Thessalonica community, rather than Imperial portraits.

The church was turned into a mosque by the Ottomans in 1590. It was re-opened after extensive restoration in 2015, as a Museum.
