Porto Maior (As Neves, Galicia) is currently the oldest dated archaeological site in Galicia, with a chronology of the main occupation levels between 312,600 and 210,700 years ago. Of particular importance is level PM4, dated to around 210,000 years ago, as it is the only European case of an occupation level characterised by an extensive anthropic accumulation of large Acheulean bifaces and cleavers. This type of occupation scenario was exclusive to the African continent and the Near East, and its recognition in Porto Maior provides a key reference to prove a close relationship between the Iberian and African Acheulean.
