Tipaza (formerly Tefessedt, Chenoua: Bazar, Arabic: تيپازة) is a Berber-speaking town on the coast of Algeria, capital of the Tipaza Province. The modern town, founded in 1857, is remarkable chiefly for its sandy beach, and ancient ruins.
Tipaza was an ancient Punic trading-post conquered by Ancient Rome and turned into a military colony by the emperorClaudius for the conquest of the kingdoms of Mauretania.1 Afterwards it became a municipium. The Roman city was built on three small hills which overlooked the sea. Of the houses, most of which stood on the central hill, no traces remain; but there are ruins of three churches — the Great Basilica and the Basilica Alexander on the western hill, and the Basilica of St Salsa on the eastern hill, two cemeteries, the baths, theatre, amphitheatre and nymphaeum. The line of the ramparts can be distinctly traced and at the foot of the eastern hill the remains of the ancient harbour. The basilicas are surrounded by cemeteries, which are full of coffins, all of stone and covered with mosaics. The basilica of St. Salsa, which has been excavated by Stéphane Gsell, consists of a nave and two aisles, and still contains a mosaic. The Great Basilica served for centuries as a quarry, but it is still possible to make out the plan of the building, which was divided into seven aisles. Under the foundations of the church are tombs hewn out of the solid rock. Of these one is circular, with a diameter of 18 m and space for 24 coffins. Commercially it was of considerable importance, but it was not distinguished in art or learning. Christianity was early introduced, and in the third century Tipaza was a bishop's see. Most of the inhabitants continued non-Christian until, according to the legend, Salsa, a Christian maiden, threw the head of their serpent idol into the sea, whereupon the enraged populace stoned her to death. The body, miraculously recovered from the sea, was buried, on the hill above the harbour, in a small chapel which gave place subsequently to the stately basilica. Salsa's martyrdom took place in the 4th century. In 484 the Vandal king Huneric (477‑484) sent an Arian bishop to Tipaza; whereupon a large number of the inhabitants fled to Spain, while many of the remainder were cruelly persecuted.
Tipaza revived for a brief time during the Byzantine occupation in the 6th century but was given the Arabic language name, Tefassed, when Arabs arrived there. The term translated means badly damaged.2
Near Tipaza at 36°33'58"N 2°28'50"E, there is Tipaza longwave transmitter, a facility for broadcasting a French speaking program on the longwave frequency 252 kHz, which can be well received in many parts of Europe.
The town and its surroundings is home to the largest Berber speaking group of western Algeria, the Chenoua people.
Another Roman town of the same name
Another town which was called Tipasa, in Latin Timesis, was located in Constantine Province, 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 m thick.
