They are attributed to the Metal Age. The Mal Paso Tower is quite well-known. Several excavations have uncovered the remains of Neolithic burials in a cave and burial remains from the end of the Iberian period. They’re quite Romanized and possibly lasted until the end of the Western Roman Empire.

Some remains of medieval ceramics from the Islamic period have also been found.
