is a Spanish locality which is placed in the province of Valladolid (Castile and León), next to the borders with the province of Segovia. It is the highest municipality of the province of Valladolid, at more than 900 m over sea level. It belongs to the historical region of Castile, concretly to Old Castile.HistoryMany are the theories about the origin of Campaspero's name, though, maybe, the most accurate is the one that indicates the former name of " Rough Field ", which has been found in numerous documents, as root of Campaspero's current toponym. Undoubtedly, the stony of the area and the rigorous of the climate served to give to this field the epithet of roughly(harshly).As the majority of the villages of the Communidad de Villa y Tierra (Community of Town and Land) de Cuéllar, to which it belonged, Campaspero should have been founded at the beginning of the 11th century, in the frame of the repopulation of the Valley of the Douro. This repopulation was entrusted to Don Pedro Ansúrez, as Valladolid's one.Since then until 1833, the locality belonged to the province of Segovia. Although, it was very linked to the province of Valladolid because of the proximity to the Comunidad de Villa y Tierra de Peñafiel (Valladolid). In 1833, Campaspero was included in Valladolid's province once and for all.
