Geghard is a medieval monastery in the Kotayk province of Armenia, being partially carved out of the adjacent mountain, surrounded by cliffs. It is listed as a UNESCO World Heritage Site with enhanced protection status. While the main chapel was built in 1215, 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".
