Don’t fear, the sewer is dry! One can now walk underground through the full length of the 2,000 year old Herodian drainage channel that ran below the street from the Siloam Pool to Robinson’s Arch near the Temple Mount. The route of the street is indicated on the drawing below:
Tom Powers has an excellent description using recent photographs and my map of this drainage system that I used in a previous blog post to explain its construction during the Hasmonean period and the Herodian bypass that was made after the construction of the southwest corner of the Herodian Temple Mount cut the earlier drain.
In an earlier post I wrote:
It will be exciting to walk again through this tunnel, but while doing so, one should also remember that in 70 AD many Jerusalemites tried to escape through this same tunnel, but were cruelly killed by the Romans when they were discovered.
