In the words of Sir John Marshall:
The Great Baths (Mohenjo-Daro-Larkana, Sindh-Pakistan):
One of the most spectacular structures at Mohenjo is the 'Great Bath', which is astonishingly well preserved and measures 180 feet north to south and 108 feet east to west. It is described as a “vast hydropathic establishment and the most imposing of all the remains unearthed at Mohenjo-Daro" by Sir Marshall.
“Its plan is simple: in the center, an open quadrangle with verandahs on its four sides, and at the back of three of the verandahs, various galleries and rooms; on the south, a long gallery with a small chamber in each corner; on the east, a single range of small chambers, including one with a well; on the north, a group of several halls and a fair-sized room. In the midst of the open quadrangle is a large swimming pool, some 39 feet long by 23 feet broad and sunk about 8 feet below the paving of the court, with a flight of steps at either end and at the foot of each a low platform for the convenience of bathers who might otherwise have found the water too deep. The bath was filled from the well, and the waste water was carried off through a covered drain. The Great Bath had at least one upper level, as evidenced by a stairway. A large amount of timber, possibly richly carved, must have gone to the building of the upper storey, judging from the quantities of charcoal and ashes found in the course of excavation."
The outer walls of the Great Bath measure between 7 and 8 feet in thickness and were lined with bitumen.
