Construction was carried out over a long period of time, so the monastery exhibits three architectural styles:
Plateresque,
Herrerian and
Churrigueresque. The east wing of the monastery, from the first half of the 16th century, was executed in
Plateresque style. The
Herrerian style church in the north wing was completed in 1602. The rest of the monastery, built in the 17th century, is of
Baroque style, and culminates with its
Churrigueresque facade work by
Pedro de Ribera.
Plateresque Style Plateresque style is so named because its decoration imitates the filigrees that goldsmiths performed on silver. This part of the building was designed by
Enrique Egas and executed by
Francisco de Luna,
Pedro de Vandelvira,
Gaspar de Vega,
Pedro Tolosa,
Diego de Alcántara and
Bartolomé Ruiz. The Plateresque decoration is clearly seen in the asymmetric windows of the eastern facade, in which skulls, shells, crosses, and other allegorical motifs are repeated. The
coffered ceiling of its
refectory features carvings of
longleaf pine, and has thirty-six
caissons corresponding to thirty-six busts of masters, priors, and knights of the
Order of Santiago. One of the most prominent is dedicated to Don
Álvaro de Luna. Instead of his effigy, there is a crowned skull surrounded by the inscription, "You, noble lords, know that anyone forgives." The image of
Carlos V, Holy Roman Emperor occupies the central place with its imperial attributes, a sword and an orb. The south side displays the shield of Spain. The old
sacristy has two ships at right angles and its dome is ribbed with ogival elements. The Plateresque work also covers friezes, columns, and
pilasters.
Herrerian Style The church completed in 1598, is a work by
Francisco de Mora, a disciple of
Juan de Herrera, architect of El Escorial. The church earned the nickname, "Escorial of La Mancha". The church, in the shape of a Latin cross, has a single
nave with five sections and a high choir. It is sixty-five meters long and twelve meters wide.
The cruise is higher and is closed in lantern shape. It is separated by a
grille decorated with the royal arms and the
cross of Saint James. The
dome, by
Antonio Segura, is adorned with gores on scallops. In its only nave, side chapels interconnect and form two aisles. The altarpiece is of Greco-Roman style with Baroque trends. It was commissioned to
Francisco García Dardero. The painting of Saint James presiding the altarpiece is by
Francisco Rizi, who was a portrait painter of
Philip IV. . Francisco de Mora. Between the sacristy and the church is the entrance to the
crypt, which has a Latin cross. Though the crypt no longer contains remains, it previously held the remains of many members of the Order of Santiago, including Doña
Urraca, the Grand Master
Rodrigo Manrique and his wife, and his famous son
Jorge Manrique. In the 17th century, the remains in the church of Santiago were relocated to a subterranean chapel under the choir. It is possible that a cell in the crypt, under the main altar, held the prisoner
Francisco de Quevedo. In the 17th century, the monastery's patio was built, including two floors of galleries. The cloister has thirty-six balconies on a closed upper floor. The west facade was planned by
Francisco de Mora, but was not built by him. It is also of Herrerian style and contains the front entrance of the church. This facade was flanked by two towers with high
spires that disappeared in the fires of 1845 and 1877.
Churrigueresque style The main facade was built in 1735 by
Pedro de Ribera, a Baroque master of the court. It is built as an altarpiece facade with carved ornamentation. The facade features four non-load bearing, decorative pilasters. The decorative carvings include dolphins, lions, heads, warriors, trophies, fruits, and two crosses of Saint James. The summit is decorated with two busts of chained Moors, and a bust of
Saint James with a cross in his left hand and a sword in his right. An inscription reads
Fidei defensio ("Defense of the faith"). At the bottom is the inscription
Caput Ordinis ("Head of the Order"), freestanding crosses, a royal crown, knights with trophies, and chained Moors. ==The old fortress==
