Odzun Church, Early Christian basilica in Odzun, Armenia.

Odzun Church is a large three-nave basilica built from pink felsite stone with arched cloisters on its northern and southern sides. The structure features a barrel-vaulted roof and sits within a cemetery containing old tombstones.

The building was constructed in the 6th century and was significantly reworked in the 8th century by Catholicos Hovhannes III Odznetski. This reconstruction shows how the site remained important to the Armenian church across generations.

The church has carried several names, including Saint Astvatsatsin, Saint Nshan, Saint Hovhannes and Khachgund. The last comes from Khachgund, a priest buried in the churchyard, for whom a carved cross-stone with an inscription was raised in 1291. A sculpted angel braces its hands against the window frame on the facade.

The church stands on the central rise of Odzun village in Lori Province. The building is surrounded by a cemetery with large basalt tombstones and khachkars from the 13th to 20th centuries. Restoration work in 2012–2014 used glass-fibre cables and fabrics to reinforce the dome and walls.

The arched funerary monument northeast of the church holds two four-metre stelae carved with Gospel scenes and the spread of Christianity in Armenia on their east and west faces, and geometric and plant motifs on their north and south faces. Each face has a different border ornament. A wine bottle with a note on the 1889 repairs was found under the dome during the 2012–2014 restoration.
