ABOVE GROUND
Beyond the Villas: Bulla Regia's Baths, Theatre and Temples
The underground villas get the fame, but Bulla Regia's forum, Memmian Baths, theatre and two temples show it was a fully working Roman town above ground too.

The largest above-ground structure at Bulla Regia is the Memmian Baths, a substantial complex of bathing rooms wrapped in arched service passages. An inscription on site credits their construction to Julia Memmia, a wealthy woman thought to be connected to the Severan imperial family, who is recorded as funding the baths as a gift to her native town — explicitly for the health and comfort of its citizens. The scale of the building is a useful reminder that Bulla Regia wasn't only a residential curiosity; it was wealthy enough, well into the third century AD, to support civic generosity on a genuinely large scale.
The forum and its temples
Bulla Regia's forum, a porticoed civic square at the heart of the town, is flanked by two temples rather than one — a capitol building to the west and the Temple of Apollo to the north. Together they mark the forum as the religious as well as administrative centre of the colonia, the space where the town's status as a full Roman city was most visibly expressed. Walking the forum's edge gives a clearer sense of Bulla Regia's civic scale than the residential quarters do, even though the underground houses get most of the attention.
The Temple of Apollo
The Temple of Apollo was built as three joined sanctuaries, its inner chamber later given an elaborate opus sectile floor — patterned stone inlay rather than mosaic — during a renovation in the early third century AD. Excavation of the temple produced a notable statue of Apollo, now held in the Bardo National Museum in Tunis rather than on site, one of several Bulla Regia finds that ended up in the capital's collections instead of staying with the ruins. The temple's position on the forum's north side underlines how central Apollo's cult was to the town's official religious life.
The Temple of Isis
Not every temple at Bulla Regia served Roman gods. A smaller Temple of Isis, dedicated to the Egyptian goddess whose cult became fashionable across the Roman world, stands on a raised podium bordered by a wall dating to the town's earlier Numidian phase — a small physical link between Bulla Regia's pre-Roman and Roman-era religious life. A flight of seven steps led up to the cella, the temple's inner sanctuary, through an open porch. It's a quieter, less-visited corner of the site, but a useful reminder of how cosmopolitan Roman-era religious practice in North Africa actually was.
The theatre
Bulla Regia's theatre is smaller than the grand civic theatres of Roman Africa's largest cities, but well preserved, and its floor includes a mosaic depicting a bear rendered with more charm than menace — an unexpectedly lighthearted detail in an otherwise formal public building. Like the temples nearby, the theatre belongs to the town's above-ground civic core rather than to the residential underground quarter, and it's easy to combine with a look at the forum and baths in a single loop across the upper part of the site. Its modest size doesn't mean modest ambition — provincial towns across Roman Africa competed to build their own theatres as a mark of civic status, and Bulla Regia's is a clear example of that pattern.
Reading the whole town, not just the villas
It's tempting to treat the underground villas as the whole reason to visit Bulla Regia and rush past everything else, but the baths, forum, temples and theatre are what turn a striking architectural curiosity into a complete Roman town. Together they show a place that functioned as a real civic centre — bathing, worship, entertainment, administration — long before and after its wealthiest residents started building their houses downward. Seeing both layers is what makes sense of Bulla Regia as a whole, rather than as a single unusual attraction. It also explains why guided visits typically move between both halves of the site rather than treating the underground houses as a self-contained stop.
