Gagi

Gagi was a fortress of northeastern Armenia, built on a height overlooking the valley of the same name. Its walls enclosed rock-cut cisterns and caves used as barracks, with a small church of Saint Sarkis on the summit. After the Georgian king David the Builder recovered the fortress from the Seljuks, it became the seat of the Vahramyan princes, a branch of the Zakarian family. Mongol forces besieged it in 1236.
