This is an accepted version of this page Khokhanaberd (Armenian: Խոխանաբերդ, Azerbaijani: Xoxanabert), also known as Khanabert (Azerbaijani: Xanabert qalası) and Tarkhanaberd (Armenian: Թարխանաբերդ), is a 9th-century mountaintop fortress near the village of Vank, in the disputed region of Nagorno-Karabakh, in the Kalbajar District of Azerbaijan.

[1] The fortress has historically been referred to by various names besides Khokhanaberd, including Tarakhana, Khavanaberd, Khokh, Khoyakhan, and Havaptuk.

[1] Khokhanaberd is first mentioned in the history of 13th-century Armenian historian Kirakos Gandzaketsi, who wrote that Hasan Jalal I fortified himself in the castle while under attack by the Mongol general Jula, brother of Chormaqan.

[2] Although Jula was unable to take the fortress, Hasan Jalal was forced to provide a yearly tribute and troops to the Mongols, as well as marry off his daughter Ruzan to Bora, Chormaqan's son.

[2] Despite this, after the succession of Güyük Khan to the Mongol throne in 1246, Bora returned to Khachen with an army to collect tribute and destroyed Khokhanaberd along with several other fortresses belonging to Hasan Jalal.
