Research (2009 and 2013) This hill fort is located in the Laciana region, 750 m SE of the town of Villablino (León). It occupies an approximate surface area of 1.6 hectares on a breakwater that descends to the N from the Cuetonidio elevations along the Sil River, which defines the site to the NE and NW. The line of the walls and a large moat can be appreciated in the S sector, where the inhabited hill connects with the mountainside. They lead to a 1050 m absolute altitude platform, covered with dense oak (grove) vegetation. The hill fort was excavated during the late 1970s by a team from the University of Salamanca led by F. Jordá Cerdá, but the results remain unpublished. In 2009 and 2013 recent archeological work was carried out in a 750 m2 area within the framework of a project of enhancement of the castro settlement in the region. These works confirmed a sequence of occupation lasting from the Second Iron Age until the Early Roman imperial period, with a possible later occupation during the Early Middle Ages. The oldest remains belong to a E-W modular wall which defends the South sector of the settlement. This slate slab wall is linked to two dwelling structures located inside: they both are circular-shaped huts, one of them with stone base and the other suggested by a groove in the slate geological substratum, two hearths, a post hole and an underground silo/garbage. The material culture associated to this soil horizon is limited: some handmade pottery, ironwork evidence, rotating granite millstones and pieces of clay plastering with plant impressions. The beginning of this occupation seems to date to the late Second Iron Age. According to carbon-14 dating, its end corresponds to a destruction level around the change of Era. The Roman presence completely modified the morphology of the settlement, both the fortifications and the interior habitat. The defensive structure was expanded with a 30 m long and 7 m wide section that gave way to the town entrance. Habitat evidence: those attached to the wall, or in an orthogonal layout complex, as well as other circular buildings in the inner part, attests to a vigorous construction activity from 40 AD or a little earlier until the mid-late 2nd century AD. Materials such as _South_ _Gaulish_ _Terra_ _Sigillata_ and thin-walled pottery enabled dating, which should be regarded in relation to ancient gold mines in the upper Sil River basin.
