The fortress is located 25 km south-west of the village of Achajur, on the left bank of the Lusadzor river, on the road leading from Achajur to the summer cottages of Sevkar and Sarigyukh. The locals call the fortress ‘Kerogli’. The fortress is located at an altitude of about 2000 meters above sea level and covers an area of more than one hectare. In the central part, you can see the foundations of stone residential buildings. Oblique slopes extend from the northeastern and partly northern sides, so there was no need for additional protective structures and strong fortress walls were built on the other side. The fortress is rectangular, stretching from south-east to north-west, 215 m long and 40-60 m wide. The 5 m wide entrance is located in the center of the fortress. The length of the eastern and southeastern fortress walls reaches 30 m, in this part there is the second - the eastern entrance of the fortress, in front of the western one. At the entrance there is a small rectangular tower 7x6 m. The southern wall, 140 m long, is more solid. The width of the wall in the southeastern part reaches up to 4 m. Here, during the excavations of two dwellings, a number of objects were discovered that were characteristic of the 1st half of the 1st Millennium BC (karases, items made of red and black ceramics, etc.).
