The most important structure in the fortress (citadel) of Mohenjo Daro is the Great Bath. It is in a rectangular shape. The pond is in the yard which is surrounded by corridors on all four sides. To get into the pond there are steps on the northern and southern sides. The bottom of the pond is made watertight using bricks and lime paste. This prevents the water from seeping down and making the water level go down.
There are rooms on 3 sides of the pond. There was a big well in one of the rooms. The water for the pond ‘ was brought from this well. There were provisions for filling the pond with water and to make the dirty water ow out into drains. Historians think that the Great Bath had a religious importance. They think that this Great Bath was used for ritual baths. The Great Bath shows the importance the Harappans gave to cleanliness. It also shows their engineering and technical skills.
