Among the architectural monuments of early medieval Armenia, compositions of Avan-Hripsime type occupy a special place. They are the results of many generations of creative searching in this architectural country. At the end of the VIIc in the historic province of Syunik in Sisavan (now Syunik district) was raised a temple (St.Grigor) of the same type, which reached us in good condition. The compositional center of the temple appears to be the space under the belfry, and four apses join it through the main axis. The temple has two entries- from the west and south.
The decorations of the temple are skillfully worked out: all its motives were well known in VI-VII cc. The Sisavan Church stand out with its relevant relieves. They are situated on the facade, and in the interior of the church. In the depth of western and southern bays the pictures of well-off men are placed.
