The Lluera caves are two small natural cavities (sometimes the denomination Cueva de la Lluera is used for the main one, ignoring the small one, and from the archaeological point of view Cueva de la Lluera I and Cueva de la Lluera II) . They contain prehistoric representations of the Paleolithic, which are found in the parish of San Juan de Priorio, in the municipality of Oviedo, Asturias (Spain). Archaeological remains from the Solutrean period (21,000 to 17,000 BP) and the final Upper Magdalenian have also been found. The first associated with part of the engravings.
