sometimes tipasa is called "tipasa in mauretania" because there was another tipasa in roman africa. indeed, another town called tipasa was located in the roman province of numidia (the reason why it is referred to as "tipasa in numidia", is in order to distinguish it from "tipasa in mauretania"). this second tipasa is located in what is now constantine province, algeria, 88 km (55 mi) due south of annaba, 957 m above the sea: it is now called tifesh. the chief ruin is that of an extensive fortress, the walls of which are 3 meters thick.
