The character of Katoghike church's decoration is connected with the artistic traditions of the time when it was built. The round cupola drum was destroyed by earthquake in 1927 (also rebuilt in by 2000), and is decorated with a 12-arch arcature. The front wall of the altar has carved khachkar-type crosses, and there are rosettes on the walls and on the spherical pendentives of the cupola where they alternate with flat arch motives.
