View looking west along the southern portion MB II revetment wall at Old Testament Jericho.
Reconstructions of the walls of Jericho suggest that there were two walls: an outer mud brick wall - which was built on top of this revetment wall - and an "inner wall" - located higher up (off the picture to the upper left) on the mound. Bryant Wood has suggested that this revetment wall, and associated mud brick walls, were not destroyed in 1550 B.C. (the "traditional" ending of the MB II archaeological period), but rather continued in use into the Late Bronze Age - being destroyed in the conquest of Joshua, about 1400 B.C.
