The first monastery to be built in the city after the reconquest by the Christians, this monastery is noted for its picturesque courtyards, the Spanish Baroque-style sacristy and significant paintings and sculpture. The church is a basilica with a crossing and side chapels, with a Capilla Mayor which contains the crypt of the "Gran Capitan", Gonzalo Fernandez de Cordoba (1453-1515). Work on the east end of S Jerónimo was begun by the 'Florentine', Jacopo Torni (1525-1526), but Siloé was responsible for the spectacular octagonal dome: supported on squinches treated as shell-niches, it has a vault of intersecting, paired arches and coffering profusely decorated with reliefs.
