Rapidum
Rapidum was a Roman settlement and fort located in Mauretania Caesariensis, nearly 100 km south of Icosium (Algiers). == History == The Romans built a fort in what is now Sour Djouab (south of present-day Algiers) during the first century of their rule in Mauretania between Castellum Tingitanum (El Asnam) and Auzia (Sour el Ghozlane), in order to expand their control of the interior of the region.
