The Great Bath of Mohenjo-daro B
1. The Great Bath at Mohenjo-daro, looking north. The side walls of the roughly 12 by 7 meter tank were constructed with finely fitted bricks and a thick layer of bitumen (natural tar) was laid along the sides of the tank to keep water from seeping through the walls and up into the superstructure.
2.Lower ledge inside the Great Bath, southern edge, looking east. At the foot of the stairs is a small ledge with a brick edging that extends the entire width of the pool. People coming down the stairs could move along this ledge without actually stepping into the pool itself.
