Case Romane del Celio

Case Romane del Celio preserves an entire block of Roman houses beneath the Basilica of Santi Giovanni e Paolo, dating from the 2nd to 4th centuries AD. You will descend into over 20 rooms across multiple levels, including private apartments, shops, a nymphaeum with original frescoes, and even Christian frescoes from when the space was secretly used for worship. The preserved paintwork features genuine reds and blues that resemble colours applied yesterday rather than 1,700 years ago.

The visit feels like exploring a wealthy Roman's basement that time has forgotten. You follow a set route through narrow corridors and chambers, with excellent lighting that brings out details in the frescoes and mosaics. The temperature drops noticeably underground (around 15°C year-round), and the silence creates an almost sacred atmosphere. Audio guides in multiple languages explain each room's function, from the confessio where early Christians may have been martyred to elegant dining rooms with intact decorative schemes.

At €8 for adults, this delivers far better value than the Colosseum's underground tour. Most visitors rush through in 45 minutes, but you can easily spend 90 minutes here if you're interested in Roman domestic life. Skip the overpriced bookshop upstairs, but don't miss room 17 with its perfectly preserved ceiling frescoes. The site gets busy around 11am when tour groups arrive, so aim for opening time or late afternoon.
