Dis-jointed. The closeup of Wilson’s Arch provides telling clues regarding the relative date of its construction. The blocks in the wall to the right of the springers show signs of chipping and shaving, indicating that the arch was built (or rebuilt) later than the Herodian wall and had to be made to fit into the wall. In contrast, the springers in Robinson’s Arch, along the southern end of the western wall, fit cleanly into their neighboring wall blocks because they were built at the same time.
