Sabratha's port was established, perhaps about 500, as the Phoenician trading-post of Tsabratan. This seems to have been a Berber name, suggesting a preëxisting native settlement. The port served as a Phoenician outlet for the products of the African hinterland. Greeks called it also Abrotonon. After the demise of Phoenicia, Sabratha fell under the sphere of influence of Carthage. Following the Punic Wars, Sabratha became part of the short-lived Numidian kingdom of Massinissa before this was annexed to the Roman Republic as the province of Africa Nova in the 1st century BC. It was subsequently romanized and rebuilt in the 2nd and 3rd centuries. The Emperor Septimius Severus was born nearby in Leptis Magna, and Sabratha reached its monumental peak during the rule of the Severans, when it nearly doubled in size. The city was badly damaged by earthquakes during the 4th century, particularly the quake of 365. It fell under control of the Vandal kingdom in the 5th century, with large parts of the city being abandoned. It enjoyed a small revival under Byzantine rule, when multiple churches and a defensive wall were erected. The town was site of a bishopric. Within a hundred years of the Muslim invasion of the Maghreb, trade had shifted to other ports and Sabratha dwindled to a village.
Archaeological site
Sabratha has been the place of several excavation campaings from 1921 onwards, mainly by Italian archaeologists. It was also excavated by a British team directed by Kathleen Kenyon and John Ward-Perkins between 1948 and 1951. Besides its that retains its three-storey architectural backdrop, Sabratha has temples dedicated to Liber Pater, Serapis and Isis. There is a Christian basilica of the time of Justinian and also remnants of some of the mosaic floors that enriched elite dwellings of Roman North Africa. However, these are most clearly preserved in the colored patterns of the seaward baths, directly overlooking the shore, and in the black and white floors of the theater baths. There is an adjacent museum containing some treasures from Sabratha, but others can be seen in the national museum in Tripoli. In 1943, during the Second World War, archaeologist Max Mallowan, husband of novelist Agatha Christie, was based at Sabratha as an assistant to the Senior Civil Affairs Officer of the Western Province of Tripolitania. His main task was to oversee the allocation of grain rations, but it was, in the words of Christie's biographer, a "glorious attachment", during which Mallowan lived in an Italian villa with a patio overlooking the sea and dined on fresh tunny fish and olives.
Erosion and weathering damage [April 2016 report ]
According to an April, 2016 report, due to soft soil composition and the nature of the coast of Sabratha, which is mostly made up of soft rock and sand, the Ruins of Sabratha are undergoing dangerous periods of coastal erosion. The public baths, olive press building and 'harbor' can be observed as being most damaged as the buildings have crumbled due to storms and unsettled seas. As the most common building material in Sabratah, calcarenite, is highly susceptible to physical, chemical and biological weathering, the long-term conservation of the monuments is endangered. Rising sea levels can also compromise the integrity of the site. This erosion of the coast of Ancient Sabratha can be seen yearly with significant differences in beach layout and recent crumbled buildings. Breakwaters set in the vicinity of the harbor and olive press are inadequate and too small to efficiently protect the Ancient City of Sabratha.
