The triangular fortress of San Chuis

The castro of San Chuis is a pre-Roman hillfort located in Allande, Asturias, declared a site of cultural interest. It sits on a peak reaching 783 metres along the ridge separating the Prada and Abaniecha river valleys. The fortified enclosure features a roughly triangular layout, bounded by a modular wall and a system of diverse ditches surrounding the entire perimeter.

In the upper neighborhood of the northeast, a total of fifteen constructions have been identified. Most present simple circular or oblong floor plans typical of the pre-Roman castreño world. However, two buildings break this pattern with quadrangular plans; one is divided into separate rooms, a feature common in the Roman castreño world, and it stands adjacent to a circular cabin.

Other structures in the upper neighborhood appear to be integrated into complex housing units with clear links to the horizontes de ocupación altoimperiales. Some of these rectangular buildings are located next to circular structures that were clearly adapted by the Roman domestic complex. The historical sequence of the site has evolved as new data from radiocarbon dating began to clarify pre-Roman horizons in nearby areas, helping to resolve long-standing debates about whether these settlements were founded in high-imperial times or had earlier origins.
