Hippo Regius
It lies at the crossroad of two major highways: the one that connects Carthage and Hippo Regius (today Annaba), and the one that connects Thabraca (today Tabarka) and Sicca (today El Kef). The town is known for its quarries, where one of the most precious types of marbles in the Roman Empire, the antique yellow marble ("marmor numidicum" or "giallo antico"), was exploited.
