Geghard is a medieval monastery in the Kotayk province, being partially carved out of the adjacent mountain, surrounded by cliffs.
The monastery complex was founded in the 4th century by Gregory the Illuminator at the site of a sacred spring inside a cave. The monastery had thus been originally named Ayrivank, meaning “the Monastery of the Cave”. The existing ensemble dates back to the 12th-13th centuries, created by the princes of Proshyan. The main church St. Katoghikeh built in the 13th century.
The most interesting part of the complex is rock structures, especially rock ledge on the second floor, where religious songs are still performed.
Geghard was prominent spiritual and cultural center of medieval Armenia, where was also seminary and a library.
