Mohenjo Daro was a city located in the south of Modern Pakistan in the Sind Province, on the right bank of the Indus River. It was built between four and five thousand years ago, and lasted until 3,700 BP. It was part of the Harrapan Civilization, and the city had at least 35,000 residents. Mohenjo-Daro means “mound of the dead”. The city was approximately one square mile in size. In 1922-1927 large scale excavations at Mohenjo-daro were carried out by R. D. Banarjee and continued by M. S. Vats and K. N. Dikshit under the direction of Sir John Marshall. E. J. H. MacKay carried out further excavations from 1927 to1931. Sir Mortimer Wheeler made small excavations in1950.
As a result of this extensive work almost one-third of the area of the old city was exposed, revealing for the first time the remains of one of the most ancient civilizations in the Indus Valley. Typical of most large and planned cities, Mohenjo-daro had planned city streets and buildings. The settlement was thought to house roughly 5,000 people, and had houses, a granary, baths, assembly halls and towers. The city was divided into two parts, the Citadel included an elaborate tank or bath created with fine quality brickwork and drains; this was surrounded by a verandah. Also located here was a giant granary, a large residential structure, and at least two aisled assembly halls. To the east of the citadel was the lower city, laid out in a grid pattern. The streets were straight, and were drained to keep the area sanitary. The people of the city used very little stone in their construction. They used two types of bricks- mud bricks, and wood bricks, which were created by burning wood. They used timber to create the flat roofs of their buildings; there are brick stairways leading to the roofs of many houses. Some houses were small, and others were larger with interior courtyards. Most had small bathrooms. Potter’s kilns, dyer’s vats, as well as metalworking, bead making, and shell-working shops have all been discovered. The people were good at irrigation and flood control. However, when the Indus River changed its course around 3700 years ago, the civilization died.
