A large apsidal extension of the interior volume of a church is called an what?

• A. Exedra
• B. Apse
• C. Choir
• D. Transept

Answer: (A)

The major curved or polygonal termination of a church’s interior where the altar sits is called the apse. This space projects beyond the main floor plan, creating a distinct sanctuary behind the nave and choir. An exedra, by contrast, is a semicircular recess used in classical architecture for seating or a formal recess in a wall, not the liturgical sanctuary of a church. The choir is the singing and clergy space near the apse, and the transept is the cross arm that cuts across the nave. So the appropriate term for that large apsidal extension is the apse.
