The church of San Juan de los Reyes, near the Puente de San Martin, was built in 1476 by Ferdinand and Isabel, in thanksgiving for the victory of Toro gained over the Portuguese allies of Juana, nicknamed “la Beltraneja.” The first architect was a Fleming, Juan Guas, one of the builders of the cathedral. The church was intended to receive the ashes of the royal founders, but after the capture of Granada it was decided to establish the mausoleum in that city, and the completion of San Juan de los Reyes was delayed till the seventeenth century. In consequence, the architecture exhibits the transition from the Late Gothic to the Late Renaissance style. “Nothing,” remarks Street, “can be more elaborate than much of the detail of this church, yet I have seen few buildings less pleasing or harmonious.” The exterior is unpromising, and is decorated, if we can use the word in such a connection, with festoons of rusty chains which fettered the limbs of the Christians in Moorish prisons. The chief entrance, to the north, was completed by Covarrubias in 1610, and is in the decadent style of architecture. It is adorned with inferior statuary, and the arms and initials of the Catholic sovereigns. The interior is composed of a single nave, two hundred feet long and from forty-three to seventy feet wide. There are four chapels on one side and three on the other. At the east end of the church is a shallow five-sided apse, forming the Capilla Mayor. Over the junction of the nave and transept is an octagonal cupola, resting on four fine pillars, with a pointed dome and a window in each face. At the west end of the church is a deep gallery, containing the choir. The altar dates from the Renaissance period, and is brought well forward into the nave. It came from the suppressed church of Santa Cruz. Above it is a blue velvet canopy, embroidered with the eagle, the symbol of St. John. The whole fabric is enriched with statuary, tracery, carving, and heraldic devices in almost reckless profusion. The yoke and the arrows--the devices of the Catholic sovereigns--and their coats of arms are repeated again and again. Among the inscriptions is one commemorating the foundation of the church. It runs: “Este monasterio é églesia mandaron hacer los muy esclarecidos Principes é señores D. Hernando é Doña Isabel, Rey y Reina de Castilla, de Leon, de Aragon, de Sicilia, los cuales señores por bienaventurado matrimonio y uñaron los dichos Reinos, seyendo el dicho rey y señor natural de los reinos de Aragon y Sicilia, y seyendo la dicha señora Reina y señora natural de los Reinos de Castilla y Leon; el cual fundaron á gloria de nuestro señor Dios, y de la bienaventurada Madre suya, nuestra Señora la Virgén Maria, y por especial devocion que le ovieron.”
