Unesco classified this site on the World Heritage List in 1997, considering that it is the “best preserved small Roman city in North Africa”.
This archaeological site preserves, within its delimitation, the vestiges of different periods of the ancient city with all its components: the monumental center (capitol, forum, market, place of the wind rose ...), the buildings of shows (theater, circus) and the public baths clearly reflect the way in which an indigenous foundation evolved during the Roman period.
