The Middle Pleistocene sile of El Sartalejo is localed in the Alagon valley of the western Southern Meseta of central Spain close to the. confluence of the Alagon and Jerte rivers. Lower Palaeolithic artefacts have been reported in this area between the Alagon and Jerte valleys for some time. Most of the sites are located in the middle terraces of the Alagon and Jerte rivers, in the widest areas of the Valleys. Indeed the Alagon valley provides a natural path through this area of the Central Cordillera between the region of Extremadura to the east and the northern Meseta.
