View of the Monastery of El Escorial
The basilica of San Lorenzo el Real, the central building in the El Escorial complex, was originally designed, like most of the late Gothic cathedrals of western Europe, to take the form of a Latin cross. As such, it has a long nave on the west-east axis intersected by a pair of shorter transepts, one to the north and one directly opposite, to the south, about three-quarters of the way between the west entrance and the high altar. This plan was modified by Juan de Herrera to that of a Greek cross, a form with all four arms of equal length. Coincident with this shift in approach, the bell towers at the western end of the church were somewhat reduced in size and the small half-dome intended to stand over the altar was replaced with a full circular dome over the center of the church, where the four arms of the Greek cross meet.
