First African Baptist Church (1865) - View of Nave looking West.
The navev/ is the central part of a church, stretching from the (normally western) main entrance or rear wall, to the transepts, or in a church without transepts, to the chancel. When a church contains side aisles, as in a basilica-type building, the strict definition of the term 'nave' is restricted to the central aisle. In a broader, more colloquial sense, the nave includes all areas available for the lay worshippers, including the side-aisles and transepts. Either way, the nave is distinct from the area reserved for the choir and clergy.
The nave extends from the entry—which may have a separate vestibule (the narthex)—to the chancel and may be flanked by lower side-aisles separated from the nave by an arcade. If the aisles are high and of a width comparable to the central nave, the structure is sometimes said to have three naves. It provides the central approach to the high altar.
