The ensemble includes the remains of the cathedral, a palace with two ballrooms and a throne room, the residence of the Catholicos and other various premises. The whole complex is surrounded by a wall.

This building, for its beauty and architectural boldness, was known all over the country and even beyond its borders. The Byzantine emperor Constantine II, who was present at the opening ceremony announced his desire to construct a similar building in Konstantinopel.The Zvartnots ruins are inscribed on the UNESCO World Heritage List.

The most famous reconstruction plan of the cathedral was developed by architect Toros Toramanian, who likely was inspired by the presentation of the three-story Noah’s Ark relief, in the Sainte-Chapelle in Paris.
