Wall of Jericho
The Wall of Jericho was a wall of defensive or flood protection from the Neolithic Pre-Pottery A phase that arose approximately 8,000 years before Christ.
One of the walls was excavated by Sir Charles Warren in 1868 at the request of the Palestinian Exploration Fund. He entered through the mud bricks of the wall without realizing what it was, suggesting that there was little interest in the site. Ernest Sellin and Carl Watzinger excavated Jericho between 1907 and 1909 and found the remains of two walls they initially suggested supported the biblical account. This finding was later reviewed and its findings dated back to the Middle Bronze Age (1950-1550 BC). The site was excavated again by John Garstang between 1930 and 1936, which again raised the idea that the remains of the upper wall were as described in the Bible. Kathleen Kenyon resumed extensive excavations between 1952 and 1958 and did not find a defensive wall of the Late Bronze Age or ceramics. Perhaps the most important finding was the evidence that the first wall suggested by Kenyon was 8000 BC based on radiocarbon dating in 7825 BC. It is surrounded and protected from a Neolithic settlement that contained an organized community of between 2,000 and 3,000 people.
