The Tower of Jericho is an 8.5-metre-tall (28 ft) stone structure built in the Pre-Pottery Neolithic A period around 8000 BC. It is one of the world's oldest stone buildings, and one of the oldest works of monumental architecture.

The ancient wall of Jericho had been discovered by John Garstang during the excavations of 1930 to 1936, which he suggested were those described in the Book of Joshua in the Bible and dated to around 1400 BC. Kathleen Kenyon discovered the tower built against the wall inside the town during excavations between 1952 and 1958. Kenyon provided evidence that both constructions dated to much earlier, to the Neolithic, the most recent era of the Stone Age, and were part of an early proto-city. The tower highlights the importance of Jericho for the understanding of settlement patterns in the Sultanian period in the Southern Levant.
