Robinson's Arch (1st Cent BC)-Jerusalem Archaeological Park. The remnant of a stairway that led pilgrims to Jerusalem Temple at the time of Christ.

You can see the base of a massive arch protruding from the Western Wall near the southern end. The arch is known as Robinson's Arch after its discoverer, American researcher Edward Robinson in 1838. At the time of Jerusalem Temple's existence, there was a big valley separating the Western Wall from the Upper City of Jerusalem, making difficult direct access to the Temple Mount. To solve the problem, series of bridges and arches were constructed linking them. Initially, Robinson's Arch was assumed to be one of those arches that lead from the Upper City to the Temple Mount. However, it is now known that, Robinson Arch connected the Temple Mount to an adjacent paved Herodian street (whose remains are also exposed) through a flight of steps at multiple angles .
