Piedras Albas, on the border with Portugal, is situated on the southern slope of the so-called Cerro del Castillo between the Erjas and Alagón Rivers and crowned by huge blocks of white quartzite which probably gave the village its name. It is difficult to date its origins but documents can be traced which point to a pre-Celtic past when it was known as Elbocoris according to some authors such as Martín Almagro-Gorbea in his “The Central Interior of Portugal and the origin of the Lusitanians“.
According to oral tradition, in prehistoric times there were settlements around the “Canchal de los dos Ojos or Peña Buraca“. It is thought that this hill at the foot of which the village is located formerly held a Neolithic settlement which was converted firstly into an Arab fortress and then into a Christian one. The Arabs left their mark in the area above the site of “The Castle”, formerly an area of vines and of which now only pink and white blocks of stone remain. Signs of Roman times include presses for both oil and olive production, the Roman road which linked Corduba (Córdoba) with Portus Cale (Oporto), and the Segura Bridge.
