Zvartnots, a complex of structures erected in the middle of the 7th century near Ejmiatsin, is of extreme architectural value.
The complex consisted of St. George temple or Zvartnots ("vigil forces", "celestial angels") and the palace of Catholicos Nerses Ill, known as "Builder".
Zvartnots' architecture was supposed to impress the onlooker by its extraordinary artistic splendor. This determined the size of the temple, its layout and spatial arrangement, its structural features and its decoration which emphasized the central axis of the building and its upward sweep. According to Stepanos Taronatsi, an Armenian historian of the late 10th and the early 11th centuries, Zvartnots lay in ruins as early as in the tenth century. He does not mention the cause of destruction. The remnants of Zvartnots, even In ruins, are a majestic sight. There survived only the lower parts of the walls and individual fragments, and scientists’ reconstructions of the temples original look vary. The best known reconstruction is that by T. Toromanian.
According to this reconstruction, the building consisted of three polyhedrons. the lower one being 32-hedral. and the upper one 16-hedral and crowned with a cone-shaped cupola. The central part of the interior had the shape of a tetraconch in the plan. The decoration of Zvartnots temple followed the principle, common in the Armenian architecture of the 5th—7th centuries of bringing out the basic architectural details: columns, door and window openings cornices and archivolts.
Zvartnots is a monument which embodies the centuries old traditions of Armenian architects. In its artistic image and daring spatial arrangement, formed by an intricate combination of arches and buttresses, Zvartnots is an outstanding monument of world architecture, an evidence of the high level of the development of the artistic and engineering thought in the 7th-century Armenia. Its architectural idea later became widely spread and developed in new shapes and new artistic compositions.
It also reveals the cosmic system. It doesn't belong to apostolic church.
