We have visited extraordinary underground villas in the Roman City of Bulla Regia (entrance 8 TND). There was an older lady, a local English guide (15 TND / hour), available, so we got the opportunity to get some explanation about the site (better than a book). The town was built in the 5th century BC as a Cartage’s move to develop the Medjerda Valley as a wheat-growing area. We have scrolled around complete and superbly preserved underground Roman rooms with great mosaics. Originally there were two stories houses, of course, the upper floors got damaged, but underground rooms, where Romans escaped before the summer heat, have survived for centuries.
