Haghartsin monastery, situated in the woodlands of Tavush region, represents an indescribable example of blend of nature with architecture. It was founded in the 10-11th centuries, though new buildings were added in the 12-13th centuries. Now it consists of St. Grigor, St. Astvatsatsin (Holy Mother of God), St. Stepanos churches and some other buildings.The refectory, due to its skillful architectural composition, is of great interest. Near Haghartsin there used to grow a huge oak tree, almost at the age of the monastery, completing the whole scene. Unfortunately, only a small part of the hollow has remained till the present day, however, it is still of much interest among the visitors, and preserves the tradition, according to which, when one makes a wish and at the same time manages to pass through the tree (hollow), it is expected to come true in the nearest future.
