In a cross-shaped church, the transepts {tran'-sept} are the transverse arms of the building and are placed at the crossing, the juncture of the nave and the choir. Transepts were added to provide additional space at each side of the altar. Several English Gothic cathedrals, such as Salisbury Cathedral, have double transepts; the second set, with shorter arms, is placed east of the first set and is closer to the apse.
