Bulla Regia — Wikipedia

Bulla Regia was a Berber, Punic, and Roman town near present-day Jendouba, Tunisia. Its surviving ruins and archaeological site are noted for their Hadrianic-era semi-subterranean housing, a protection from the fierce heat and effects of the sun. Many of the mosaic floors have been left in place; others may be seen at the Bardo Museum in Tunis. There is also a small museum connected with the site.
