Tegher Monastery is an early 13th-century Armenian monastery and church located on the southeastern slopes of Mount Aragats near the modern village of Tegher, and across the gorge from the village of Byurakan in the Aragatsotn Province of Armenia. It was built for Princess Khatun, the wife of Prince Vache I Vachutian who had purchased the district of Aragatzotn from the Zakarian brothers. The architect Vardapet Aghbayrik designed Tegher and the monasteries of Saghmosavank and Hovhannavank during the 13th century. The monastery survived intact during a time when Mongol invasions plagued the lands.
