What did kathleen kenyon find at Jericho?

The British archaeologist Kathleen Kenyon found several important things at Jericho. Her excavations from 1952-1958 revealed a number of neolithic structures and artifacts, including the famous Jericho walls, which are believed to be the oldest city walls in the world. Kenyon also found evidence of a large stone tower that was built in the 8th millennium BCE. This tower is known as the 'Jericho Tower' and it is believed to be the oldest known architectural structure in the world. In addition, Kenyon found evidence of a number of neolithic burials and a number of artifacts that suggest that Jericho was a major center of trade during the neolithic period.
