Bagras or Baghrās, ancient Pagrae (Greek: Πάγραι; Armenian: Պաղրաս, romanized: Paġras), is a town and its nearby castle in the İskenderun district of Turkey, in the Amanus Mountains.

Strabo's Geographica mentions it as being on the borders of Gindarus, "a natural stronghold" leading to the Amanian Gate or Amanides Pylae over the Amanus Mountains.

[1] The castle of Pagrae was erected c. 965 by the Byzantine emperor Nikephoros II Phokas, who stationed there 1000 footmen and 500 horsemen[2] under the command of Michael Bourtzes to raid the countryside of the nearby city of Antioch.

[4] It was then rebuilt about 1153 by the Knights Templar[4] under the name Gaston (also Gastun, Guascon, Gastim) and held by them or by the Principality of Antioch until it was forced to capitulate to Saladin on 26 August 1189.

Bağras was never integrated into the complex defensive system that the Armenians built along the Taurus and Anti-Taurus Mountains of Cilicia from the 12th through the 14th centuries.
