Jericho, the Round Tower - 8,000 BC - The first remains of the town are at tel es-Sultan. The "tel" is a small hill that is the result of many habitation layers on top of each other. In the middle of the tel is an open area in which a huge round stone tower lies. Its age is estimated at thousands of years, belonging to the first settlement in Jericho. In the middle of the tower is a perfectly preserved stairway. The stones of this building are not made from mud, but from natural stones. It is this tower which gives Jericho its status as oldest city on earth, because nowhere else a tower or similar building has been found from such an old age. The tower also points to the existence of some sort of communal system through which the construction would have been organised. 固opFoto
