Odzun Monastery is located on a plateau above the canyon of the Debed River near the town of Alaverdi, Lori region. Odzun Monastery is the most interesting construction in the north of Armenia, only because it was built in the VI century. The temples of this century in Armenia are single, and there is only one in the north. It differs in size and layout of the building. Odzun Monastery is one of the only specimens of this type. Instead of the vestibule the temple is surrounded by a wall with arches, which is almost never seen in Armenia. On the west side, two belfries are attached, but this is a novelty of the XIX century.
