The castle is built on a pre-existing medieval necropolis with anthropomorphic tombs carved into the rock.
The defensive walls were constructed using local sandstone blocks extracted from the immediate surroundings.
It transitioned from a defensive fortification to a noble palace during the late Middle Ages.
The site was abandoned for centuries and suffered significant decay before being acquired and restored by the Hermandad de Campoo de Suso.
Architecturally, it maintains the distinct style of the 'torres señoriales' (seigneurial towers) common in Northern Spain.
Argüeso Castle is a rare example of a rock-cut castle in Cantabria, featuring foundations carved directly into the sandstone. The structure consists of two residential towers, the older dating to the 12th century and the newer to the 14th century, connected by a central courtyard. It served as the ancestral seat of the Marquis of Argüeso and the House of Mendoza. The current restoration preserves the layout of a medieval defensive fortress including battlements and internal chambers. It is situated in the Híjar Valley, overlooking the high plateau of the Campoo region. The site functions as a museum space displaying historical reconstructions and period-appropriate furnishings.
