New research on the city walls of Pisidian Antioch was begun in 2010 as part of a joint study between the
Austrian Archaeological Institute and the Süleyman Demirel Üniversitesi in Isparta (TR). The research
aimed at a complete documentation of the monument, and to evaluate its appearance and layout in the Anatolian context. The walls encompass the entire urban territory that was laid out on the high plateau of a hill raising up to c. 1,200 m above s. l. In the south an unusual bastion with doubled round towers and a complicated entrance system are preserved, whereas the walls in the north and the east are nearly extinct now. The earliest walls consist of a high-quality opus caementitium base layer with ashlar walls on top, probably erected in early Roman Imperial age. Later additions were made extensively in the Late Antique periods.
Building material was taken from Roman Imperial necropoleis; a cautious assumption for a terminus post quem allows for a construction date in the course of the 4th century A.D.
