The monastic complex consists of a church, chapel, and gavit (narthex)
The church at Hayravank, St. Stepanos, was built during the late 9th century. It has a quatrefoil cruciform central-plan structure with four semi-circular apses and a conical dome directly above.

You can see 2 of the 4 semi-circular apses directly in the middle, the chapel to the far left, and the gavit on the far right.
