Castle of La Alameda

The castle of La Alameda is located in the municipality of Madrid, Spain, and was built during the medieval period by the Castilian civilization. Its origins trace back to the 15th century, constructed within the village of La Alameda, a settlement repopulated in the 13th century in what is now the Barajas district. This location, taking advantage of a small hill, became strategically important during the late Middle Ages.

The fortress was likely commissioned by Diego Hurtado de Mendoza between 1431 and 1476, serving to assert his authority over the surrounding area. Historical records reveal that after the Battle of Toro in 1476—a critical event in Castilian succession disputes—the castle provided shelter for supporters of Queen Juana la Beltraneja. As the lordship passed to the Mendoza family, the castle also became intertwined with Madrid’s noble circles through a dowry granted by King Juan II of Castile to Inés de Ayala and Ruiz Sanz Zapata, firmly linking it to the influential Zapata family of the late medieval period.

In the latter half of the 16th century, specifically from 1575, Francisco Zapata y Cisneros, the first Count of Barajas and lord of La Alameda, initiated significant modifications. Under his guidance, the castle underwent transformation from medieval fortress to Renaissance palace. Enhancements included expanding the residence with new wings on the eastern and southern sides and constructing a prominent keep tower, reflecting evolving architectural tastes and functions of noble residences during this period. Its gardens also replaced the original defensive moat, indicating a shift toward comfort and aesthetics.

The castle hosted notable figures of its time. In 1580, Fernando Álvarez de Toledo, known as the Duke of Alba, was recorded as a visitor. Later, in 1599, Queen Margaret of Austria stayed within its walls. The building also saw darker episodes when the third Duke of Osuna died there after a short captivity between 1622 and 1624, further marking its role in aristocratic and political affairs.

A disastrous fire in 1697 severely damaged the castle, leading to its abandonment. During the 18th and 19th centuries, the ruins became a source of building materials. Stones were repurposed for other constructions in the area, including the pantheon of the Fernán Núñez family. The site suffered further harm during the Spanish Civil War in the early 20th century when a machine gun nest was established close to the castle as part of Republican defensive lines.

Archaeological interest in the site began in 1996, revealing a much longer history of occupation. Excavations uncovered remains from the Bronze Age through to Roman times, demonstrating that the location had been settled continuously since around 2000 BCE. Since 2010, the partially restored castle has functioned as a museum managed by the Madrid City Council and is recognized as a Bien de Interés Cultural, an official category protecting Spain’s heritage sites.
