A transept is a part of a church or cathedral that intersects the main body of the building, creating a cross-shaped floor plan. It is typically located between the nave, where the congregation sits, and the altar area. The transept often contains additional chapels or altars and can enhance the overall architectural design of the structure.
In many Gothic and Romanesque churches, the transept is prominent and can be either short or long, depending on the design. The presence of a transept allows for more space and can improve the flow of movement within the church, accommodating larger gatherings and ceremonies.
