Baghaberd, Medieval castle in Syunik Province, Armenia.

Baghaberd stands on a triangular plateau atop a rocky spur of the Barkushat range, west of Kapan near where the Voghji and Geghi rivers meet. Vertical cliffs above the Voghji and its tributary the Giratagh protect the western side, so the walls were built mainly along one line. Ruins show double walls with towers.

The fortress was founded in the 4th century by Baghak of Sisak Nahapet and served as an important regional stronghold. After the destruction of Kapan in 1103, it became the final capital of the Syunik kingdom.

During the 10th–12th centuries, under the Kingdom of Syunik, the fortress held the riches and thousands of manuscripts of Tatev Monastery and other Armenian monasteries, moved there for safekeeping in unfavourable political conditions. In times of danger the surrounding population also took refuge inside its walls.

The fortress is only accessible by sport utility vehicle due to its remote mountain location and rough terrain. The long journey of around 376 kilometers from Yerevan should be considered when planning a visit.

According to Stepanos Orbelian's history, Prince Andovk of Syunik stored provisions at Baghaberd and waited for the army of Sassanid King Shapur II. His men defeated three of the king's units by rolling rocks down the cliffside, then Andovk fled to Constantinople, where Emperor Theodosius I received him with honours.
