The monastery complex of Horomayr is a very important religious center of Armenia (it was mentioned since VIIc.). It’s located south-east of the Odzun village. The monastery consists of two monumental complexes: one situated on the Debed river on the left shore, and the other on the plateau. The main church of the first group, St. Nshan was built by Zakare and Ivane spasalars in 1187 from basalt stone. Above the church’s only northern entrance there is a relief of Holy Mother and baby Christ. The bell tower was built in 1290. Next to Horomayr, there is another church and a small chapel built in 1201. To the north of the monastery complex, there is a square-schemed bell tower with a big absit, built in 1301, and next to it St. Arakyal’s chapel ruins. Around the complex, there is a monastery cemetery (XIIIc.) with cross-stones and headstones. Plateau’s monumental complex consists of two churches (the south one was built by the monastery priest Samvel together with architect Grigor Kargortsi in 1206) and a bell tower between them.
