A side-note on the real walls of Jericho: the stories and legends of the bible/torah were collected and expanded in 700 BCE by King Josia to serve several political purposes. He needed a narrative to show that he was a direct descendent from the legendary forefathers Abraham, Mozes and David, and he needed a narrative to show that the tribe of Judah could reunite all other tribes of the region and take leadership for it. Many of the stories were created to demonstrate this power. So also the story of King Joshua trying to capture the city of Jericho. In the 13th century BC, the settlements that existed were never fortified: ie they had no walls. "In the case of Jericho, there was no trace of a settlement of any kind in the thirteenth century BCE, and the earlier Late Bronze settlement, dating to the fourteenth century BCE, was small and poor, almost insignificant, and unfortified. There was also no sign of a destruction. Thus the famous scene of the Israelite forces marching around the walled town with the Ark of the Covenant, causing Jericho's mighty walls to collapse by the blowing of their war trumpets, was, to put it simply, a romantic mirage", write Israeli archeologists Israel Finkelstein and Neil Asher Silberman in their eye-opening book: "The Bible Unearthed".
