The church complex Tegher is situated on the southern slope of Mount Aragats. It consists of a church and an anteroom and was built in the 13th century under the patronage of Vache Vachutian’s wife – Mamakhatun. The anteroom is of great interest, on the roof of which, from the south-western and north-western corners, small chapel-like churches were built. This anteroom has a special place among the architectural monuments of Armenia, due to its costructional composition. There is a stunning view, opening from the territory of the complex to Byurakan observatory.
