Buimanco is a depopulated town located in the province of Soria, in the autonomous community of Castile and León, Spain. It belongs to the municipality of San Pedro Manrique, in the Tierras Altas region. This town was depopulated in 1965 due to the purchase of land for pine plantations, and many of its former inhabitants emigrated to other cities such as Tudela, Barcelona, and Madrid.
Although currently uninhabited, Buimanco remains a place of historical and cultural interest for the descendants of its former inhabitants.
