Cerro del Bu

The Cerro del Bu is a Chalcolithic archaeological site (4500-3000 BC) on the Bu hill in Toledo, Spain, occupying a promontory on the left bank of the Tagus river, south of Toledo city[1]. The hill's steep relief and isolation provided a strategic defensive position[2]. Surface remains include construction stones with evident foundations on naturally irregular ground[2]. This hilltop settlement represents Copper Age occupation in the Tagus river valley[1].
