Zvartnots Cathedral

Zvartnots Cathedral (meaning "celestial angels"), now in ruins, is a 7th-century centrally planned aisled tetraconch type Armenian cathedral built from 643-652by the order of Catholicos Nerses the Builder. The Cathedral was dedicated to St. Gregory the Illuminator and was built in the place, where a meeting between King Tiridates III and Gregory the Illuminator was supposed to have taken place. Zvartnots remained standing until the end of the 10th century, though historical sources are silent about the cause of its collapse. Zvartnots Cathedral is listed in the UNESCO World Heritage Sites.
