The Community of Madrid initiates the process to declare the Casa del Bosque, a 16th-century Renaissance gem in Buitrago del Lozoya, linked to the Mendoza family.
The Casa del Bosque, a 16th-century recreational villa located in Buitrago del Lozoya, is about to receive the highest heritage recognition from the Community of Madrid. The regional government has officially started the process to declare it a Heritage Asset (BIP) in the category of Monument, as published in the Official Bulletin of the Community of Madrid (BOCM).
This historical complex, located just 87 kilometres from the capital, is a unique example of Renaissance architecture in the region. Linked since its origins to the powerful Mendoza lineage, the property breaks away from the Castilian sobriety of the time to embrace the most advanced artistic currents of Renaissance Europe.
A Renaissance Oasis by the Lozoya River
The protection process covers not only the old residential pavilion but also its historic garden, a waterwheel, shearing houses, a dock, and the perimeter wall that extends to the Lozoya River. The entire complex was conceived as a place of rest and escape for the nobility.
The history of the property dates back to 1368, when the Mendozas received the lordship of Buitrago. It was Íñigo López de Mendoza y la Vega who, in 1596, commissioned the master builder Diego Varela to construct the residential palace. The design, inspired by Italian Renaissance villas and Palladian models, was structured around a large central hall crowned by an imposing dome.
From Hunting Ground to War Hospital
The building has witnessed historically significant moments. It hosted King Philip III in 1601 during a documented visit. During the War of Independence, it was looted by the Napoleonic army and functioned as a military hospital. Later, in the Civil War, it served as a strategic position for Republican forces on the Puentes Viejas front.
After the abolition of the lordship regimes in the 19th century, the complex came into the hands of the Community of Madrid in 1983. Since then, its state of conservation has deteriorated to a consolidated ruin, although it has not lost its historical magnetism.
An Investment of €281,390 to Prevent Collapse
To prevent its definitive collapse, the General Directorate of Cultural Heritage promoted a consolidation and archaeological restoration intervention between 2022 and 2023 with an investment of €281,390.61. The works, led by the specialist teams Almenara and Reno Archaeology, managed to halt the collapse of the brick drum that crowns the building and recover decorative elements, pavements, chimneys, and plaster coats of arms.
Thanks to this intervention, the Casa del Bosque has halted its deterioration and is preparing to showcase its new status as a protected Monument. For the residents of Buitrago del Lozoya and the Sierra Norte, this declaration represents a tourist and cultural boost that will highlight one of the region's most unique corners.
The next step will be the processing of the file, which includes a period for public information and objections, before the final approval by the Governing Council of the Community of Madrid.
