Handaberd

Handaberd (), also known as Lekh Castle () or Lev Castle, is a 9th century fortress located in the Kalbajar District of Azerbaijan, near the village of Knaravan, between the villages of Chapli and Ganlykend, on the right bank of the Levçay River. It was built by Atrnerseh I, ruler of the Armenian Principality of Khachen, who resided there.
History.
One of several castles in the highlands of Kalbajar, Handaberd was constructed over the Ayrım Gorge, on a high mountain ridge surrounded by thick forest, from the right bank of the Levçay River flowing by Ganlykend village. Handaberd is first mentioned as "Handu berd" by the 10th century Armenian historian Movses Kaghankatvatsi, who wrote in his work "History of the Country of Albania" that the fortress was built by Prince Atrnerseh of Khachen in the second quarter of the 9th century. Atrnerseh, a member of a branch of the Siunia dynasty, ruled over an area approximately corresponding to the historical Armenian province of Artsakh. Handaberd was located in the Tsar province (also known as Upper Khachen) of the Principality of Khachen․ It served as Atrnerseh's residence as well as a prison for prisoners sentenced to death.
According to the inscription on one of the khachkars kept at Dadivank, a nearby Armenian monastery, from 1142 to 1182 Handaberd belonged to Hasan I Vakhtangyan, prince of Upper Khachen. Around 1250, it is mentioned in the history written by the Armenian historian Kirakos Gandzaketsi. Some time after the initial construction under Atrnerseh, the fortress was significantly expanded.
Handaberd's inscriptions were studied by the French orientalist Marie-Félicité Brosset in the mid-19th century. Less than a kilometer to the east of the fortress is a medieval monastery complex bearing the same name, which has also been excavated.
The fortress has historically been referred to by various names and renderings, such as Lev (also the Armenian name for the Levçay River), Levaghala, Levkala, Levonaberd, Lohaberd, Handberd, and Handuberd.
