Castellum Tidditanorum (modern Tiddis in Algeria) was a Roman city in Numidia, established as a military settlement in Augustus' time (r. 27 BCE-14 CE). Built on a steep hillside of red earth with commanding views over a deep canyon, the Romans adapted their rule of town planning to the sloping topography, with streets winding their way up to the summit. Castellum Tidditanorum had gates, a forum, thermal baths, industrial installations (fillers, oileries, and pottery workshops), religious buildings, and a sanctuary of Mithras.
