Palacio de los Hornillos

Palacio de los Hornillos is a country mansion in Arenas de Iguña featuring multiple architectural sections with steep roofs and stone masonry throughout. The structure displays different materials in each section to reflect the varying functions housed within its rooms.

This mansion was designed in 1897 by British architect Ralph Selden Wornum for the Duke of Santo Mauro, blending English neoclassical style with Spanish building traditions. The fusion of foreign and local influences remains visible in the building's appearance today.

The palace hosted King Alfonso XIII as a temporary resident before he moved to another royal residence, and later attracted film productions to its grounds. These dual roles reveal how the building held different importance for the region across generations.

This remains a private property owned by the Duke of San Carlos and access to the grounds requires special authorization beforehand. Visitors should check in advance whether tours are available, as the estate is not freely open to the public.

The estate is surrounded by artificial ponds and staircases that skillfully organize the landscape around it. These water features were deliberately incorporated into the overall design of the property.
