Zvartnots Cathedral (literally 'celestial angels cathedral') is a 7th-century centrally planned aisled tetraconch type Armenian cathedral built by the order of Catholicos Nerses the Builder from 643-652. Now in ruins, it is located at the edge of the city of Vagharshapat (Etchmiadzin) in Armavir Province of Armenia. In 2000 UNESCO added Zvartnots Temple together with churches in Echmiadzin (Vagharshapat), Saint Hripsime and Saint Gayane to World Heritage Sites.
