CASTLES MADRID

Castle of Villaviciosa de Odón sits west of Madrid as a palace-fortress complex steeped in Spanish nobility and conflict. Built in 1496 by Andrés Cabrera y Beatriz Fernández de Bobadilla, the Marquis of Moya, the castle was destroyed during the 1521 Revolt of the Comuneros but reconstructed in 1583 under commission by royal architect Juan de Herrera, who created an asymmetric profile with distinctively varied towers. King Philip V later purchased the estate in 1738 and granted it to his son, commanding restoration by architect Ventura Rodríguez. The fortress endured sieges, served as a notable prison, and functioned as a military garrison throughout its history. Today it houses the Archives of the Spanish Air Force, preserving both its architectural heritage and the broader narrative of Spanish monarchy and statecraft.

Castillo de la Coracera is a 15th-century fortress in San Martín de Valdeiglesias, Madrid, originally commissioned by Álvaro de Luna as a royal residence and hunting lodge. The castle served as a royal residence for Isabella the Catholic when she was proclaimed heir to Castile, and features elements referencing earlier 12th-13th century construction. Well-preserved through 20th-century restoration efforts, the fortress now hosts exhibitions, conferences, and concerts under the management of the Castillo de la Coracera Foundation established in 2003.

Castillo de Puñoenrostro in Torrejón de Velasco, Madrid, was founded between 1430 and 1440, though its first written record dates to 1455. The fortress was likely promoted by Gutierre Gómez de Toledo, connected to the House of Alba. By 1465, the castle had passed to Álvar Gómez, secretary to King Henry IV, before Pedro Arias Dávila took possession as lord of Puñoenrostro. Throughout the 16th century, like other castles in the region, it served as a prison for notable members of the royal court. After becoming privately owned, the municipality acquired the castle in 2002. Listed on the Red List of endangered heritage by Hispania Nostra in 2006, it underwent substantial restoration completed in April 2012, preserving this significant example of 15th-century military architecture.

The Castillos de los Marqueses de Valderas in Alcorcón are a pair of remarkable early 20th-century mansions built between 1915 and 1917 in Saxon architectural style. Originally constructed for José Sanchiz de Quesada, the Marquis of Valderas, these palatial residences have hosted Spanish royalty, including King Alfonso XIII in 1920. During the Spanish Civil War, the castles served as military observation points. Today, one castle houses the Municipal Museum of Art in Glass (MAVA) while the other functions as the Municipal Library, preserving their cultural significance within an urban park setting just outside Madrid.

Castle of Buitrago del Lozoya is a 14th-15th-century Gothic-Mudéjar fortress built from brick and masonry within the medieval town walls near Madrid, distinguished by its nearly square plan and seven towers of varied shapes. The castle's towers feature distinctive rows of openings crowned by semicircular horseshoe arches, reflecting the architectural synthesis of Christian and Islamic building traditions. Once the residence of the Marquis of Santillana and his descendants, the fortress was designated a Cultural Heritage site in 1931.

Castillo de Villarejo de Salvanés, also known as Torre del Homenaje, is a 13th-century fortress built by the Order of Santiago just 50 kilometers from Madrid. The castle showcases a distinctive architectural design with a central square tower measuring 16 by 22 meters, surrounded by eight cylindrical turrets functioning as buttresses rather than corner towers—an uncommon arrangement in Spanish military architecture. Restored and designated National Historic Heritage Site in 1974, the keep now houses a tourist office and interpretation center, offering visitors insights into its medieval history and panoramic views of the surrounding countryside.

La Alameda's Castle is a 15th-century fortress built between 1431 and 1476 by the Mendoza family on a small hill near Madrid. Originally constructed as a military fortification with a moat, rectangular floor plan, and two towers, the castle underwent a dramatic transformation in 1575 into a Renaissance leisure villa complete with grand windows, formal gardens, fountains, and tree-lined paths, becoming a favored summer retreat for Madrid's nobility. Though devastated by fire in 1697 and subsequently abandoned, the castle remains one of only four surviving medieval fortifications in Madrid, now accessible via public transit to the Alameda de Osuna district.

Castillo Viejo de Manzanares el Real, popularly called Plaza de Armas, is situated on the outskirts of Manzanares el Real in Madrid, on the edge of the Manzanares River beneath the southern slopes of La Pedriza in the Sierra de Guadarrama. Though its foundation date is unknown, it predates the famous Castillo Nuevo built in 1475. On October 14, 1383, King Juan I of Castile granted the fortress to the House of Mendoza, establishing the señorío of Real de Manzanares. Built in Mudéjar style with granite stone and brick banding, the castle featured a square plan with cylindrical towers at three corners and a larger keep. The old fortress declined when the Mendoza family constructed their new palatial castle nearby, leaving only two walls standing within a planted enclosure.

The Castle of Fuentidueña de Tajo, perched on a hilltop overlooking the town in Madrid's Community, dates to the 12th century with significant extensions in the 14th century during the reigns of Kings Alfonso VI and Alfonso VIII.

Though now in ruins, the castle remains an important example of Castilian military architecture and is protected under Spanish historical heritage law, with free public access to explore its strategic position above the landscape.

The Castillo de Calatalifa represents an extraordinary example of 10th-century Andalusian culture in the Madrid region, commissioned by Caliph Abderramán III. Located in the southwest of Villaviciosa de Odón, this archaeological site was occupied from the 9th century until the Castilian conquest, with its name meaning 'Castle of the Caliph.' The settlement served not merely as a fortress but as a military administrative center with horticultural agriculture and livestock herding, strategically positioned on the Guadarrama valley communication axis. Declared a Cultural Interest Archaeological Zone, the site preserves notable cisterns from its original Andalusian occupation period.

Castle of Malsobaco is a historic Islamic fortress in Paracuellos de Jarama, Madrid province, originally constructed during the 9th century as part of the defensive system of the Middle March under Emir Muhammad I. Built strategically on a hill overlooking the Jarama valley, the castle was documented during the Reconquest and later ceded to the Order of Santiago in 1180, remaining under their control until the sixteenth century. Declared a Site of Cultural Interest in 1985, today the ruins preserve the castle's floor plan, remains of a lateral tower, perimeter walls, and a historic cistern, offering visitors insight into medieval Islamic military architecture and the region's complex historical transitions.

Castillo de Alcalá la Vieja is a medieval fortress in Alcalá de Henares, Madrid, rising on a clay promontory in the Henares River valley. Built by Muslims in the 9th century under Emir Muhammad I, the castle originally served as "Qal'at'Abd al-Salam," a simple watchtower integrated into the al-Andalus defensive system, before falling to Christian forces in the early 12th century. Today, two defensive towers remain standing after recent restoration, along with ruinous remains of other tower structures and walls, preserving evidence of over a millennium of occupation. The castle's designation as "la Vieja" (the old) reflects its centuries of abandonment after the 13th century, making it a valuable archaeological site documenting the region's Islamic and Christian heritage.

Castillo de Alboer stands on a prominent hill in southern Villamanrique de Tajo, Madrid, overlooking the Tajo river plain from a chalky cliff. Originally constructed in the 9th century by the emir Mohamed I of Córdoba and rebuilt by the Almoravids during the 12th century, the fortress formed part of a critical defensive triangle for the Order of Santiago alongside the castles of Alharilla and Salvanés. This small fortification served as a strategic outpost during the Emirate, Caliphate, Almoravid, and Almohad periods until its destruction in 1478 during the War of Castilian Succession. Now in ruins with limited architectural elements visible, the site remains freely accessible and reflects centuries of frontier conflict in the Middle March.

Castillo de Torremocha dominates the landscape of Santorcaz in eastern Madrid at 800 meters altitude, positioned above a small ravine flowing into the Anchuelo stream. Built in the 14th century over 12th-century foundations, it constitutes the sole surviving vestige of the defensive system surrounding Santorcaz, which included seven wall towers and the Church of San Torcuato. The fortress features a distinctive oval plan with only its southern side straight, reflecting its integrated role within the town's fortifications. Historically serving as an episcopal residence before becoming a prison, the castle notably held Cardinal Cisneros for six years. Currently undergoing restoration with completion expected in 2026, the castle represents medieval ecclesiastical and defensive architecture.

Palacio de la Zarzuela is a historic country palace and hunting lodge located in Fuencarral-El Pardo on the outskirts of Madrid, Spain. Commissioned by King Philip IV in 1627, the palace was designed by renowned architect Juan Gómez de Mora in a restrained Baroque style inspired by the Renaissance villas of Andrea Palladio. Situated on Monte de El Pardo hill, the building features the sober rectangular design characteristic of Madrid's baroque period. Since 1975, the palace has served as the official residence of the Spanish monarch, including King Felipe VI, and also functions as royal working offices. While not open to the public, the palace remains a significant architectural landmark representing centuries of Spanish royal history and aesthetic refinement.

The Nido de Ametralladora in Madrid represents a significant vestige of the Spanish Civil War, constructed in 1938 as part of a defensive network created by Republican forces. These machine gun nests, or casamatas, were semi-buried structures designed to minimize exposure to artillery while allowing operators to fire heavy weapons through their single openings. Several examples remain visible in Madrid's green spaces, including the Parque del Oeste and Ciudad Pegaso, serving as physical reminders of the conflict's urban dimensions and the civilian experience of war in the Spanish capital.

Castle Aulencia stands on a strategic hilltop near Madrid where the Aulencia River meets the Guadarrama River, featuring a distinctive slender tower surrounded by a double wall with six cylindrical towers. Likely built in the 15th century under Alonso Álvarez de Toledo, the castle held importance in Madrid's medieval defensive network and regional feudal hierarchy. Today the structure survives as atmospheric ruins approximately 20 meters high, commanding views of the surrounding landscape. Listed on Hispania Nostra's red list of endangered heritage sites, the castle remains a notable historical landmark accessible to visitors exploring Madrid's lesser-known fortifications.

Castillo de Casasola crowns a rocky promontory overlooking the Tajuña River valley in Chinchón, Madrid province.
