Final answer:
The chevet area of a medieval church is typically reserved for clergy and religious ceremonies, but the main part of the church is often open to the public.
Step-by-step explanation:
Chevet is a term used in architecture to refer to the rounded or polygonal apse of a medieval church.
The chevet is typically located at the east end of the church and is usually reserved for clergy and religious ceremonies.
While the chevet area may not be accessible to the general public, the main part of the church, including the nave and transepts, is often open to the public for worship, tours, and other activities.
