Ancient History of Avdat
Before the end of the 1st century BCE a temple platform (the acropolis) was created along the western edge of the plateau. Recent excavations have shown that the town continued to be inhabited by the Nabataeans continuously from this period until its destruction by earthquake in the early 7th century CE. Sometime towards the end of the 1st century BCE the Nabataeans began using a new route between the site of Moyat Awad in the Arabah valley and Avdat by way of Makhtesh Ramon. Nabataean or Roman Nabataean sites have been found at excavated at Moyat Awad (mistakenly called Moa of the 6th century CE Madeba Map), Qatzra, Har Masa, Mezad Nekarot, Sha'ar Ramon (Khan Saharonim), Mezad Ma'ale Mahmal and Grafon.
Avdat continued to prosper as a major station along the Petra-Gaza road after the Roman annexation of Nabataea in 106 CE. Avdat, like other towns in the central Negev highlands, adjusted to the cessation of international trade through the region in the early to mid 3rd century by adopting agriculture, and particularly the production of wine, as its means of subsistence. Numerous terraced farms and water channels were built throughout the region in order to collect enough run-off from winter rains to support agriculture in the hyper arid zone of southern Israel. At least five wine presses dated to the Byzantine period have been found at the site.
