The old Convent of Santo Domingo, where Jaime I laid the first brick, is now an army HQ. It is one of the most impressive buildings in the city with its gothic Chapel, the Capilla de los Reyes, classified as a National Artistic Monument since 1931. The Claustro Mayor (the cloister), built between the 14th and 15th centuries, has five arches with different styles supporting the dome and the Aula Capitular (the Chapter House) was built in the 14th century. Of neo-classical style is the Capilla de San Vicente Ferrer with one main nave, a transept and crosspiece dome featuring a lantern. Finally, there is the Renaissance entrance, commissioned by Felipe II, the courtyard, garden and refectory.
