Sedvu Monastery of the Holy Nshan is located in the Sedvu Gorge, 3 km south of the village of Kachachkut in Lorri Marz. Of the 13th-century complex, the main church, the chapel attached to its north, the small porch built in front of the southern entrance, as well as sections of the wall and auxiliary buildings, have survived.
The Holy Sign is a long, single-nave church. The semi-cylindrical vault is divided into three sections inside by arches rising from the piers. To the east is a semi-circular apse, while the entrances are on the western, southern and northern walls.
The architectural historian Patrick Donabedian identifies a synthesis of different traditions in the Sedvu church. He links the three windows of the apse and the absence of a high altar to Georgian church architecture. At the same time, the modest sculpture follows Armenian forms. The monastery lacks the narthex characteristic of Armenian complexes, and the specialist compares the small, four-column portico in front of the southern door with Georgian porticoes.
A chapel was also built adjacent to the monastery. The Sedvu fortress, located 0.5 km south-east of the monastery, served as a watchtower fortress in the 13th century. Only the half-ruined tower has survived from the fortress, which is in danger of collapse.
