History.
The fortress was first mentioned by Hovhannes Draskhanakerttsi (John V the Historian) in the 9th-10th centuries in his "History of Armenia" as being controlled by the Armenian noble Bagratuni family. He wrote that in 924, after losing a battle at the island of Sevan, the commander and chief Beshir went on to attack the fortress of Kakavaberd. He was later beaten by Gevorg Marzpetuni. The same event is recorded in the book "Armenia and the Armenians" (1874) by James Issaverdens where he writes,
 
In the 11th century it passed over to the Pahlavuni family, and in the 12th–13th century to the Proshyan family for whom the nearby town is named. Kakavaberd was last mentioned in the year 1224 when after losing a battle that took place near Garni, Ivane Mkhargrdzeli found shelter there. 
Muratsan has also mentioned the fortress in "Gevorg Marzpetuni" (1896), a historical novel set in Armenia in the 10th century.
