Resumen: Uribe Kosta is one of the regions of Biscay with the highest density of prehistoric archaeological sites, due in large part to the first-order abiotic resources provided by the flint from the flysch. However, the intensity of research and degree of knowledge of the archaeological heritage have not been commensurate with its importance. Only in recent years specific projects to address this deficit have been established.Abstract: Uribe Kosta is one of the regions of Biscay with the highest density of prehistoric archaeological sites, due in large part to the first-order abiotic resources provided by the flint from the flysch.
