Pico San Chuis Hill Fort in San Martín de Beduledo, in the borough of Allande, was discovered by José Lombardía Zardaín, a resident of Allande. The first excavations were carried out between 1962 and 1963 under the joint supervision of Elías Domínguez and Francisco Jordá. The digs resumed in 1979, under the sole supervision of the latter, in short summer campaigns until September 1986.
The sequence of occupation of San Chuis Hill Fort commenced in the 8th century BC, when the first continuous slab wall was built, which subsequently served as the base for another modular structure raised during the second Iron Age. Its defensive structure was reinforced by several lines of ditches arranged on its southern flank.
The Roman presence is manifest from the middle of the 1st century AD in a context marked by intense mining activity in the abundant gold deposits in the surrounding area. Later occupation is ruled out nowadays as it was based on a misidentification of pieces of pottery that are actually regional productions dating from the Early Roman Empire.
