Zvartnots is the oldest and largest church in historical Armenia. It was built in the middle of the 7th century near Ejmiatsin by Catholicos Nerses II (known as 'the Builder'). Zvartnots is one of the extreme architectural values. The complex consisted of St. George temple or Zvartnots and the palace of Catholicos Nerses II. The cathedral contained four W-shaped piers to support its large dome, which in turn divided the cathedral’s interior and exterior spaces. Destroyed in the 10th century, its evocative ruins now stand in a semi-industrial landscape near Zvartnots Airport and were included on Unesco's World Heritage List in 2000.
