The Church of Odzun is located in the village by the same name near Alaverdi in the Republic of Armenia (coord. 41-08 / 44-40). The church has been attributed to the 6th or 7th century with additions made by Kat'olikos Yorhan Awjnec'i (717-728 AD) during the 8th century. An inscription on the lintel of the south portal indicates that Yorhan commissioned T'ovmas, the architect and sculptor, to rebuild the church. The church is a large, longitudinal cruciform church inscribed within a rectangular form and it is constructed of pink felsite stone.

On the interior, four free-standing piers support the cupola with two additional piers at the west end of the space. The small bell towers on the east end of the church were constructed in the late 19th century. Restoration was undertaken in 1889 and again during 1949-1950.

The monument has two narrow stelae set between double arches set upon a high platform. The stelae are divided into panels within which are carved figural, floral and geometric motifs. There are scenes referential to the conversion of Armenia to Christianity, as well as scenes from both the Old and New Testaments.
