Tvarageghtsi Basilica
Tvarageghtsi, southwest of Koghb, is a three-aisled basilica dating to the sixth and seventh centuries. Its worship space was divided into three longitudinal parts. The church was rebuilt in 1258.
The partly ruined walls and openings are prominent remains of the former settlement. A medieval cemetery lies nearby. About half a kilometre north, a hilltop preserves the site of a tenth- to twelfth-century chapel. The name Tvarageghtsi applies to both the church and the abandoned village.
