Baghaberd is one of the medieval defense constructions in Armenia. It is 15 km to the north-west of Kapan on the left bank of the river Voghchi, on the triangle top of the mountain. According to the legend Baghaberd was built by Baghak from Sisak nahapet /forefather/ family.

   In the 4^th century the prince Andovk Syuni beat the army of the Persian king Shapuh under the walls of Baghaberd. In 4-12 centuries Baghaberd played an important military-political role being one of the centers of Syunik principality and later Syunik kingdom. In the end of the 12^th century it was destroyed by Seljuks. Being naturally protected with high rocks of deep canyons Baghaberd was surrounded with tower-form thick and high walls. In some places the rocks had been planed and changed into natural walls. There was a citadel on the triangle top of the mountain. The entrance of it was from the north-eastern part. Here the ruins of Baghaberd are well preserved. One can see ruins of Baghak monastery.
