One Bay of Transept, Winchester Cathedral
The transept is the area set crosswise to the nave in a cruciform ("cross-shaped") building in Romanesque and Gothic Christian church architecture. The transept separates the nave from the sanctuary, whether apse, choir, chevet, presbytery or chancel. The transepts cross the nave at the crossing, which belongs equally to the main nave axis and to the transept.
