This image is the Great Bath in Mohenjo-Daro. Located on the citadel, this ruin contains at its center an 8-foot-deep, 39-foot-long, and 23-foot-wide rectangular bathing pool built from waterproofed brick. The pool is surrounded by a series of small dressing rooms, one of which contains a well that supplied water to the bath. Used water was removed from the pool via a 6-foot-high drain that ran along the west side of the Great Bath. The people of Mohenjo-Daro used the bath for hygienic purposes, and some archeologists theorize that the Great Bath might have also been used in religious rituals. To support this theory, archeologists point to the baths of later Hindu temples and the bathing rituals that remain an important part of modern Hinduism.
