Tiddis Ruins

Tiddis (Castellum Tidditanorum) is a Roman city built on a dramatic hillside in the Gorge of Khreneg near Constantine, Algeria, often called the City of the Gods for its many sanctuaries. Founded as a defensive castellum of the Confederatio Cirtense, the 40-hectare site features paved streets, a monumental gate, baths, tanneries, and temples to Mithras, Vesta, and Saturn. A considerable number of water cisterns addressed the hilltop's scarcity. The site preserves numerous houses carved into the cliff slopes along with the original rampart. Occupied from at least the 4th century BC, Tiddis persisted as a small Christian village within the ruins until the 11th century.
