The "great bath" is without doubt the earliest public water tank in the ancient world. The tank itself measures approximately 12 meters north-south and 7 meters wide, with a maximum depth of 2.4 meters.
The Great Bath is situated along a north-south street with a drain covered with limestone blocks. In the background is the so-called Granary, while in the foreground are the walls of several domestic structures.
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.
