Great Bath

The Great Bath is one of the best-known structures among the ruins of the Harappan Civilization, excavated at Mohenjo-daro in present-day Sindh province of Pakistan [1]. Archaeological evidence indicates that the Great Bath was built in the third millennium BCE, soon after the raising of the "citadel" mound on which it is located [1]. The Great Bath of Mohenjo-Daro is called the "earliest public water tank of the ancient world" [1]. It measures approximately 12 metres by 7 metres, with a maximum depth of 2.4 metres [1]. Two wide staircases, one from the north and one from the south, served as the entry to the structure [1]. A ledge 1.4 metres high extending the entire width of the bath is at the lower ends of these stairs [1]. The floor of the tank was watertight due to finely fitted bricks laid on edge with a gypsum plaster, and the side walls were constructed in a similar manner [1].
