On the site of the Athenian Agora there are traces of human presence dating to the prehistoric period and more specifically to the Late Neolithic Period (3000 BC). In particular, twenty water-collecting wells have been located on the hills south of the Agora. Together with the pottery findings which mark the time of their sealing, these wells represent the earlier traces of habitation in the Agora area, as the Neolithic settlement of Athens expanded primarily along the south slope of the Acropolis. On the main area of the Agora only one Neolithic well has been discovered and a burial of an approx. 30-year old man, 1.65 m in height.  There are no material remains of the settlement to which these wells provided water: perhaps the people of that period inhabited the nearby caves, on the foothills of the Acropolis.
