The Jericho site originally occupied by the Natufian culture is greatly expanded during the eighth millennium BCE under a culture known to archaeologists as the Aceramic, or Pre-Pottery Neolithic A, who build a wall seventeen feet (five point two meters) high around the settlement.

They erect on the west side a round tower, twenty-three feet (seven meters) high, with an internal flight of steps.

The world's people are comparatively few, the technologies simple, and resources plentiful, but the community's indigenous inhabitants evidently require this kind of protection.

We can surmise that the people of ten thousand years ago differed little from us in being wary of strangers, covetous of resources, and inclined to violence.

The settlement ends around 7370 BCE.
