Step-by-step explanation:
The central space in a Christian church is called the nave. The nave is the long hallway that runs down the center of the church. It is usually crossed by a structure called the transept, which gives the church its cross-like shape.
On either side of the nave, there are auxiliary hallways known as aisles. These aisles were added so that pilgrims could enter the church and move through to the apse without disturbing a mass that might be taking place. The apse is a semi-circular extension at the end of the nave that holds the altar.
