The main structures of the monasteries erected by Prince Vache Vachutyan—the Church of Zion in Saghmosavank (1215) and the Church of Karapet in Hovhannavank (1216-1221)—belong to the same type of cross-winged domed structure with two-floor annexes in all the corners of the building. Subcupola space predominates in the interiors of both churches, which is reflected in the exterior shapes of these structures.
