The cities of Harappan civilisation were well planned. They were protected by forts. Wide roads, public wells, multi-storeyed- buildings and well-planned drainage system are the important features of Harappan cities. The drainage system is a great achievement of our ancestors. The importance was given to cleanliness and public health is a model for the present. This system of town planning cannot be found elsewhere in the ancient civilisations. In Mohenjodaro a great tank for public bath, now called the ‘Great Bath’ was found. There was rooms on all sides. Six large granaries and the quarters for laborers are found in Harappan cities. Lothal was a popular harbor in those days.
