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. Small sockets at the edges of the stairs could have held wooden planks or treads.
3.Lower ledge and Drain outlet, Great Bath, looking west. At the southwestern corner of the sloping floor, a small drain first passes through the massive walls of the tank and connects to a corbeled arch drain that curves along the edge of the northern terrace of the granary to the west.
4.Great Bath, looking north. The tank would have been open to the sky, but the surrounding structures would have been roofed. The sidewalls and parts of the floor have been conserved using modern replica bricks. The original eroded wall and corner are visible on the left and center. The colonnades around the tank have also been reconstructed.
