It used to be one of the most significant religious and cultural centers of the Medieval Armenia. In 1033 Grigor Magistros built the first church of the monastery, naming it after Gregory the Illuminator. The structure of this church resembles a dome hall with two-floor sacristies on both sides of the stage. The outer attire of the church is rather discreet. To the South from this minster is situated the St. Nshan cupola church (1051).

The third church of the complex, St. Katoghike (1203-1214), is located in the vicinity of St. Nshan and was built by architect Vetsik putting into effect the decree of Duke Vasak Khaghbakyan. This church constitutes a rectangle construction, cross-vaulting from inside, with two-floor sacristies in each of its four corners. The Katoghike church has, perhaps, the most sumptuous attire among all the churches of the monastery complex.

The fourth church of the complex is St. Haroutyun, which was raised in 1220. It has a cylindrical-drum resembling dome. In Kecharis there are numerous kachqars (cross-stones) dated to XII-XIII cc., which impart vividness to the monastery, turning into its integral particles. One of the most important constructions of the complex is the architect Vetsik’s tomb-cross stone (XIII c.).

The churches of the complex have been destroyed and restored reiterate times. In 1998-2001 Kecharis Monastery Complex was entirely reconstructed by the means of benefactor Vladimir Haroutyunyan, and today it is the Residence Complex of Kotayk Diocese.
