Apamea, military and administrative centre since the Hellenistic period, has been excavated for forty years by the « Centre belge
de recherches archéologiques à Apamée de Syrie ». The actual program focuses mainly on the north-eastern area of the city and
on the junction between the urban area and the defensive circuit wall. Excavations yielded an occupation from the beginning of
the Roman period to the 12th c. A.D. Several hydraulic buildings were uncovered, as well as a complex water supply system, which was
still active at the end of the Byzantine period.
