Pool of Siloam (Hebrew: בריכת השילוח‎) (Breikhat Hashiloah) is a rock-cut pool on the southern slope of the City of David, the original site of Jerusalem, located outside the walls of the Old City to the southeast. The pool was fed by the waters of the Gihon Spring, carried there by two aqueducts.

The Pool is a deep, walled ditch, through which a clear stream of water runs, that comes from under Jerusalem somewhere, and passing through the Fountain of the Virgin, or being supplied from it, reaches this place by way of a tunnel of heavy masonry. The famous pool looked exactly as it looked in Solomon's time, no doubt, and the same dusky, Oriental women, came down in their old Oriental way, and carried off jars of the water on their heads, just as they did three thousand years ago, and just as they will do fifty thousand years hence if any of them are still left on earth.

We went away from there and stopped at the Fountain of the Virgin. But the water was not good, and there was no comfort or peace any where, on account of the regiment of boys and girls and beggars that persecuted us all the time for bucksheesh." (Page 583-4).
