 The first evidence of human stationary presence in the current city is the settlement of Ametzagaña, between South Intxaurrondo and Astigarraga.The unearthed remains, such as carved stone used as knives to cut animal skin, date from 24,000 to 22,000 BC.The open-air findings of the Upper Paleolithic have revealed that the settlers were hunters and "Homo sapiens", besides pointing to a much colder climate at the time.
