The street was built over a drainage system constructed of large and beautifully dressed white stones.[1] From the Pool of Siloam the street climbed up moderate steps that led up to today's Western Wall Plaza. Various shops and stores were situated along its central portion, at the foot of the Temple Mount (along today's Western Wall).[63] Among these were likely shops where sacrificial animals could be bought as well as exchangers allowing pilgrims to exchange currency and provide them with the Half Shekel ritual tax each Jew was annually obliged to pay for Temple maintenance. At the southwestern corner of the Temple Mount stood the street's most important junction.
