Tiddis

Tiddis, also Castellum Tidditanorum ( Latin for " fort of Tidditaner " ), was an ancient Roman city in the North African province of Numidia in what is now Algeria. It lies on a hill above the river Rhumel, about 15 kilometers northwest of Cirta (now Constantine), a Roman colony, whose territory Tiddis belonged.

The site has been partially archaeologically explored and excavated. Finds from the necropolis in particular show that Tiddis was an indigenous settlement originally, which was coined Roman over time. Among the excavated buildings include a spa complex and a temple of Saturn.

From Tiddis came the Roman senator and commander Quintus Lollius Urbicus. His statue stood as the base exhibits, on the forum; the mausoleum of his family was located north of the city.

In late antiquity (from the 5th century at the latest) was Tiddis seat of a bishop ( the remains of two Christian basilicas have been discovered ). As Tiddi it is a titular of the Roman Catholic Church.
