Glorious walls of the Middle Ages Askeran fortress are visible on the approach to the town, already from the road leading to Tigranakert Reserve, 14 km east of Stepanakert. In the XVIII century it underwent reconstruction and has established present appearance. The ramparts have a thickness of 2 m and a height of 9 m and round towers are interconnected by narrow passages. The embrasures are walled. You can climb on the wall through a vertical entrance. This Karabakhian fortress played an important defensive role during the Armenian-Tatar clashes in 1905 - 1906, respectively, and the Turkish raids in 1918 - 1920 years. Defensive design extends more than 1.5 kilometers along both banks of the river Kar-Kar.
