- a large necropolis with the funerary Basilica of St Salsa
- the Archaeological park which includes most of the monuments uncovered
- and the Royal Mauritanian Mausoleum, on the west Sahel plateau of Algiers, at 11 km south-east of Tipasa.
This ancient coastal city was first a Carthaginian trading centre, whose necropolis is one of the oldest and one of the most extensive of the Punic world (6th to 2nd century B.C.). During this period, Tipasa played the role of a maritime port of call, a place for commercial exchanges with the indigenous population. Numerous necropolis testify to the very varied types of burial and funerary practices that bear witness to the multicultural exchange of influences dating back to protohistoric times.
Tipasa comprises a unique group of Phoenician, Roman, palaeochristian and Byzantine ruins alongside indigenous monuments. The Roman period is marked by a prestigious ensemble of buildings, comprising very diversified architectural typologies. The monumental, circular funerary building, the Kbor er Roumia, or the great Royal Mauritanian Mausoleum, associates a local architectural tradition of the basina type, to a style of stepped truncated roof covering, the result of the different contributions, notably Hellenistic and Pharaonic. other relics include the remains of a Basilica, cemetery, baths and an Amphiteatre.
From the 3rd to the 4th centuries A.D. a striking increase in Christianity is demonstrated by the multitude of religious buildings. Some are decorated with high quality mosaic pavings, illustrating scenes from daily life, or geometric patterns. The Vandal invasion of the 430’s did not mark the definitive end of prosperity of Tipasa, but the town, reconquered by the Byzantines in 531, gradually fell into decline from the 6th century.
