Bulla Regia is an archaeological site in northwestern Tunisia, a former Roman city near modern Jendouba called officially Colonia Aelia Hadriana Augusta Bulla Regia. It is noted for its 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 situ; others may be seen at the Bardo Museum, Tunis. There is also a small museum connected with the site.(Wikipedia)
