Chashma-Ayub is located near the Samani mausoleum. Its name in Persian means Job’s spring due to the legend according to which Job (Ayub) visited this place and brought forth a spring of water by the blow of his staff on the ground. The water of this well is still pure and is considered healing. The current building was constructed during the reign of Timur and features a Khwarazm-style conical dome uncommon in Bukhara.
