# Sigüenza Cathedral

The Cathedral of Sigüenza, officially Catedral de Santa María de Sigüenza, is the seat of the bishop of Sigüenza, in the town of Sigüenza, in Castile-La Mancha, Spain. It was declared Bien de Interés Cultural in 1931.
It is dedicated to Santa María la Mayor (the Virgin Mary), the patron saint of the city of Sigüenza. It dates to January 1124 when the bishop Bernard of Agen (1080–1152) reconquered the city from the Muslims, during the reign of Urraca of León, daughter of Alfonso VI of León and Castile. He had already been appointed bishop in 1121 by the archbishop of Toledo, Bernard of Sédirac, of the Order of Cluny. Alfonso VII of León and Castile (1126–1157) granted privileges and donations to increase the population, unifying two towns: the upper around the castle and the lower one, the Mozarabic, around the channel of the Henares River.
The Gothic central nave dates to the 15th century. In the 16th century the Romanesque lateral apses were destroyed to build the ambulatory. The two outer towers of the main facade have merlons.

## Historical context

The archbishop of Toledo Bernard of Sédirac had Bernard of Agen come to his diocese of Toledo to become bishop of Sigüenza in 1121, although the city was still under the control of the Almoravids.
A letter from Queen Urraca of Leon dated February 1, 1124 granted the church and its bishop the tithe of Atienza and Medinaceli. Bernard of Agen established the "Roman rite" and suppressed the "Mozarabic rite". During his term of about thirty years, he received donations from the king Alfonso VII of León and Castile. The city was divided into the "Segontia inferior" and the "Segontia superior." After the reconquest, the two were united as a single city that passed to the Cathedral chapter.
The bishop died on the battlefield in the year 1152, succeeding him in the bishopric his nephew Peter of Leucate.

## Stages of building

In a document of 16 September 1138 Alfonso VII of León and Castile granted the land for the church.
A document from 1144 says that Bernard of Agen rebuilt a primitive cathedral "with a double wall and tower," possibly on the remains of an old Visigothic or Mozarabic church, Santa María Antiquíssima. María del Carmen Múñoz Párraga believed that this was on the spot where the current cathedral is located.
The Romanesque temple had a floor plan of three naves and a head with five apses staggered from the sides to the much larger central one. On either side of the facade was a defense tower.
The five altars of the apses were consecrated by the end of the 12th century.
Under bishop Arderico (1178–1184) the Cathedral chapter was moved to the cloister. Bishop Rodrigo (1192–1221) built the wall of the main facade and the lower part of the towers. The 13th century rose window on the southern side of the transept is ornamented with arches and circles.
The Gothic central nave is from the 14th century and the rose window on the main façade from the 15th.
In 1936 during the Spanish Civil War the cathedral was damaged. From 1943 to 1949 the Segovian sculptor Florentino Trapero supervised the restoration of damaged sculptures.

## Exterior
### Western facade and atrium

The main facade, on the west side, is Romanesque with later Neoclassical and Baroque additions. It has three doors divided by two buttresses.
The atrium, built in 1536, consists of twenty-one limestone columns, topped by chiselled lions, and measures 48 x 24 meters. On the north side of the atrium, the Contaduría del Cabildo has three Plateresque windows. In 1783 the bars and the two forge doors were carved with the shield of the commissioning bishop Francisco Javier Delgado Venegas.

#### Main doors

The middle door, called the "Puerta de los Perdones," is built with a semicircular arc and archivolts supported on columns with a capital. Above it is a pediment with a medallion in Baroque bas-relief representing the scene of The imposition of the chasuble on Saint Ildefonsus and a Romanesque rose window of the 13th century to illuminate the central nave.

#### Towers of the main facade

These towers, which were initially isolated, were built with defensive lookouts and later joined the wall. On both sides of the main façade, the two sandstone towers rise, with a square floor plan and three lower rooms with small Romanesque windows -one on each side- and in the fourth section with double windows with round arches. body with merlons and some stone spheres. The tower on the right, called "las Campanas", has a height of 40.5 meters, with an internal staircase of 140 steps, its last body was added in the 14th century, the bishop Pedro Gómez Barroso (1348–1358), who also had stone ashlar covered with the initial work, made in masonry and with the shields of the bishop and the king Peter of Castile placed on the wall of the fourth floor. The tower on the left, called "Don Fadrique", has a height of 41.7 meters and was completed in the 16th century, has the date of 1533 and the inscribed coat of arms of the bishop Fadrique de Portugal.

### Southern facade or del mercado

Turning through the tower of las Campanas is the south facade, corresponding to one end of the transept of the cathedral. In the central nave (higher), you can see the Gothic ogival stained glass, separated by buttresses, with the eaves, resting on brackets, with animal forms, alternating with metopes decorated with plant motifs. The windows of the nave lateral (bottom) show the Romanesque-ogival transition, with eaves and cornice of blind arcades.

#### Puerta del mercado

Further east, we find the Puerta del Mercado, formerly "Puerta de La Cadena", which overlooks the Plaza Mayor, Romanesque style, from the 12th century; this door is covered by a closed portico, Neoclassical style, built in 1797 by the architect Bernasconi commissioned by the bishop Juan Díaz de la Guerra. On the portal, a Romanesque rose window of transition, from the 13th century, with a very original tracery design.

#### Torre del Gallo

The Gallo tower dates from the early 14th century and was originally a military watchtower to transmit signals that could be seen from the Castle of Sigüenza. It has undergone several restorations over the years. On the central nave, the lantern tower is from the Spanish postwar period.

### Northern facade

It is analogous to the one on the opposite side, with a different rose window; in this facade, the tower is on the sacristy of Wilgefortis, in the north arm of the transept; the height of this tower is that of the central nave, and remains unfinished.

### Eastern facade

On this façade, corresponding to the head of the temple, the presence of the ambulatory that powerfully replaced the five chapels, which were originally Romanesque, stands out. The lantern tower and the tall Gothic windows correspond to the presbytery.

## Interior

The cathedral, is currently composed of a Latin cross plant, with three naves, ample transept and head with a large apse, which it contains the main chapel, surrounded by the ambulatory.
It is 80 meters long by 31 meters in width, from one extreme to the other crossing, and 28 m, in length, in the other naves. The central nave, just over 10 meters wide, is 28 m high, the lateral 21 m.
The naves are separated, by enormous pillars, which are each composed of twenty columns attached to capitals of vegetable theme, where the arc-doubleaus and formero arcs are supported. From the capitals, the stony nerves, which form the ogival vaults of rib vault, in general are of simple crossery (with two diagonal nerves), although there are two sexpartite vaults, on the sides of the transept or even octopartite, on the lantern tower. Three of the four pillars that frame the choir are different from the rest of the building, consisting of large cylindrical columns with Romanesque ornamentation in the lower part and Gothic in the upper one.

### Left nave or that of Gospel

The plant of the temple was changing with time, since in the beginning there were no lateral chapels and this is still the case of the Epistle nave that only has an altar and some sepulcher attached to the wall of the choir, on the other hand, on the Gospel nave, chapels were built that reach the adjoining wall of the cloister.

#### Parish of San Pedro

The first chapel on the left side at the foot of the cathedral is known as the parish of San Pedro. It is located, in the place where there had been old monastic dependencies, in the west gallery of the cloister with entrance by the cathedral. It is work of the 15th century, built in 1455 by order of Bishop Fernando Luján (1449–1465) and which was dedicated to Corpus Christi. Its cover is Plateresque, made by Francisco de Baeza, where the shield of the patronage bishop is shown. The grid is Gothic-Plateresque of Juan Francés made in 1533. At the end of this century, the parish of San Pedro was moved to the right of the main chapel and since then it has been known by this name.
It was greatly transformed and enlarged by the bishop Pedro de Godoy in 1675, who added three sections to the vault with the same Gothic style of starry rib vault, in spite of corresponding the work at the end 17th century. The main altar presides over an image of Saint Peter, and under this statue is the Santísima Trinidad work of the sculptor Mariano Bellver y Collazos of 1861, carved in wood and polychrome. It is represented by an iconography inspired by the models of Spanish Baroque: Father God seated, holding in his left hand globe, beside him also seated Jesus Christ carrying a cross and among them the Holy Spirit with Dove shape. The group is located on a cloud in which two angels contemplate the scene surrounded by cherubs. The plant is rectangular, quite elongated, since it occupies the entire western part of the cloister.
On the wall of this chapel is the sepulcher of the first founding bishop Fernando Luján of the 15th century, it is Gothic with scenes on three reliefs of the life of saint Catherine of Alexandria placed on top of the recumbent figure, this sculpture of the bishop. It is located on an arch that gives way to the baptistery and in front of the viewer, it was probably moved from its original place during the works of the 17th century, you can read an inscription that says: "El señor obispo Lujan. Año MCCCCLXV. Último electo por el cabildo".

#### Puerta de San Valero

It shows a mixture of styles such as Renaissance pilasters, Mudéjar arabesques and Gothic arches, although it is from the beginning of the 16th century, it was built by Domingo Hergueta. This door gives entrance to the cloister, where is the chapel of San Valero, the oldest in the cathedral, with a Romanesque floor and a Gothic iron gate.

### Crossing

It has a length of more than 36 meters and the same height as the central nave. After the Spanish Civil War of 1936, during the restoration works of the cathedral, a lantern tower was built in the center of the crossing. In the Romanesque period the crossing was without any type of altars or altarpieces, at the beginning of the 16th century and in Plateresque style the ones of Wilgefortis and Fadrique de Portugal were placed on the north side and on the south side it has the door that gives the main square of the city with a Romanesque rose window, the Chapel of the Doncel and the altar of Our Lady of the Milk.

It gives way to the cloister, where in that part is the Puerta del Jaspe of 1507, in yellow and red marble; it is the oldest Renaissance part of the cathedral.

#### Reredos

It was normal for the cathedrals of the Middle Ages to be placed under the protection of the relics of a martyr, and for that purpose the bishop Bernard of Agen brought to Sigüenza those of the martyr Wilgefortis, from the 4th century, from Aquitaine.
The reredos is located at the northern end of the transept and was commissioned by the bishop Fadrique de Portugal. Executed as a large mausoleum in limestone, it is dedicated to Wilgefortis. It shows the perfect conjunction between architecture, sculpture and painting which is typical of Renaissance-Plateresque art. Architecturally takes the form of a triumphal arch of three bodies, traced by Alonso de Covarrubias in 1518 and realized by Francisco de Baeza, with a vault of semicircular arch with coffers and on both sides niches with images of the evangelists and the fathers of the Church, as well as scenes of the virgin Mary and saints, all between columns on pedestals. In the middle part of the great reredos there is a silver urn with the relics of the saint, protected by an iron gate of Juan Francés. In the attic there is a high relief of the Virgin Mary surrounded by angels.
In the lower part, behind the reredos and inside the semicircular arch, is where the altarpiece itself is, formed by two bodies and three streets, the central one wider and higher than the lateral ones, with six paintings on a table of Juan Soreda made between 1525 and 1528. The central table of the upper body represents the Deesis and the five remaining scenes from the life of the martyr: Wilgefortis and her sisters in front of Catelio; Wilgefortis and her sisters deliberate about their fate; Wilgefortis comforts one of her sisters; Decapitation of Wilgefortis and Wilgefortis enthroned, the latter in the central street of the lower body. The image of Wilgefortis enthroned is inspired by the engraving of Marcantonio Raimondi of Our Lady of the Cloud by Raphael. The martyr is sitting with a book in her hand and the palm of martyrdom in the other. In the frieze painted in the building of Classical architecture that shelters the throne of the saint, four works of Hercules are represented, with a meaning symbolic symbolism in relation to the virtues of the martyr, which he preferred death rather than yield to earthly pleasures, just as Hercules had to fight with beasts -as allegories of vices- to achieve immortality. It was the moralizing message of Renaissance to present the exemplary life of Wilgefortis and her sisters, as Santiago Sebastián says:
   ... for to express that she was as virtuous and strong as Hercules himself.

#### Mausoleum of Fadrique de Portugal

The mausoleum of Fadrique de Portugal is Plateresque style and made by mandate of the aforementioned bishop under the design of Alonso de Covarrubias while the reredos of Wilgefortis was built, with the corner on the north part of the cathedral crossing, therefore it was made about 1520. The execution of the reredos was carried out by Francisco de Baeza and his collaborators Sebastián de Almonacid and Juan de Talavera, finalizing the project for the year 1539, date of the death of the bishop in Barcelona, from where he was transferred and buried in this place. The reredos consists of three bodies plus bench and attic with three streets. On the bench there is a card that alludes to the bishop and various adornments of grotesques and vegetal motifs, in the first body in the central part there is a large shield with the bishop's arms and two niches on both sides with the images of St. Andrew and St. Francis, the second body inside a niche is the image of Bishop Fadrique kneeling in the company of two clerics, with two other images on the side streets also inside niches of St. Peter and St. Paul, on this body there is a relief of a Pieta and on both sides the shields of the patron and to finish in the attic a polychrome Calvary.

The entrance to the chapel is made through an iron gate executed by Juan Francés between 1526 and 1532, the portal is Plateresque style and was built by Francisco de Baeza. In the interior there are several burials, standing out in the center of the pantheon the mausoleum, of Renaissance style, of the parents of the doncel, Fernando de Arce and Catalina de Sosa, supported by lions and with recumbent statues of both, the head of her on a cushion, his on laurels, indicating that he died fighting. It also highlights, on the wall, the Plateresque sepulcher of Fernando Vázquez de Arce, bishop of Canary Islands, counselor of Ferdinand II of Aragon and brother of the doncel, which acquired the chapel to the la Cerda family-former owners from the 14th century, in order to serve as a funeral chapel for him and his family, signing the decree by which they acquired the right to burial on January 9, 1487.
The sepulcher placed on three lions is under a niche in semicircular arch, with the statue of the doncel in alabaster, is dressed in armor and with the cross of Saint James in the chest, the fist of a sword and a small dagger can be seen in the waist, the head is covered with a bonnet that fits completely, but what stands out most is that it is not a recumbent figure, asleep, but that he is reclining, with one leg over the other and supports the half-built arm, in the attitude of reading a book that he holds open in his hands, in the front of the tomb two pages hold the coat of arms and it is ornamented with delicate carvings in candilieri. All the work is polychrome. The date of realization of this funerary set is between 1486, the year of the death of the doncel, and 1504, in which it is quoted in his father's testament as already made in the chapel of the cathedral.
