The monastery complex Kecharis was erected in the XI century in Tsakhkadzor. In the 12th-13th centuries, Kecharis was considered a major cult centre of Armenia, which had a higher school. The complex consists of three churches, two chapels and a porch, to the west of which, another church with its porch. The main temple is the church of St. Gregory, the first building of the monastery erected by Grigor Magistros Pahlavuni in 1003. The Surb Nshan church is a small structure erected in the XI century, probably soon after the first church. To the south of this church stands the church of Katogike, which was built in the time of Prince Vasak Khakhpakyan or Proshyan (the first quarter of the 13th century) by the architect Vetzik, in memory of which the original cross-stone carvings were staged. The chapel adjacent to the church of St. Gregory served as the burial-vault of the founder of the monastery of Grigor Magistros Pahlavuni, dated to the 11th century. The church of St. Arutiun was built in 1220. There are many burial places in the church, perhaps it was a family burial vault.
