Terme Achilliane

The Terme Achilliane are the remains of a Roman bathing complex lying beneath the Cattedrale di Sant'Agata on Piazza Duomo in Catania, Sicily. The baths belong to the Roman period, broadly the 1st to 3rd centuries AD, when Catania was a prosperous provincial city with public bathing establishments typical of Roman urban life. The surviving structures are underground, and visitors reach them by a stair on the right side of the cathedral. The same Roman masonry that the Norman builders reused when they raised the cathedral in the late 11th century is part of this story, because the baths gave the later church its foundation. What is preserved consists of vaulted brick and stone chambers, passages and traces of the heating and water arrangements that characterised Roman thermae. The setting is atmospheric: the low vaulted rooms sit below the level of the modern piazza, which has risen over the centuries because of repeated earthquakes and the lava flows of Etna that buried much of ancient Catania. The archaeological character is that of a ruin seen in situ rather than a curated display, with the visit organised as a short walk through the surviving rooms. The site is managed within the integrated archaeological itinerary of Catania, with a combined ticket introduced from June 2026, and it is run alongside the Roman theatre and amphitheatre. Restoration work has consolidated the vaults and made the stair and passages safe for visitors, though the rooms remain compact and damp, as expected for structures below the water table of an old city. Visitors interested in how the cathedral, the Roman city and the lava layers fit together will find the baths a useful complement to the church above. Opening arrangements change, so the official archaeological park website should be checked before a visit.
