apses
Curved cathedral ends
Apses is the plural of apse, a semicircular or polygonal recess in a building, typically at the east end of a church behind the altar.
The architectural feature creates a domed or vaulted space that often houses religious imagery or seating for clergy: The cathedral's apses were decorated with Byzantine mosaics.
