Wilson`s Arch is the modern name for the ancient stone arch whose top is still visible today, where it is supported against the Northeast corner of Jerusalem`s Western Wall, so that it appears on the left to visitors facing the Wall. It once spanned 42 feet (13 m), supporting a road that continued for 75 feet (23 m) and allowed access to a gate that was level with the surface of the Temple Mount during the time of Jesus.
