More like Chicago. This means they must have had some form of government and zoning, but we don't know what gave this government its authority. Cities were oriented to catch the wind and provide a natural form of air conditioning. And they were clean. Most homes were connected to a centralized drainage system that used gravity to carry waste and water out of the city in big sewer ditches that ran under the main avenues, a plumbing system that would have been the envy of many 18th century European cities. Also, in Mohenjo-Daro, the largest public building was not a temple or a palace, but a public bath, which historians call the Great Bath. We don't know what the Great Bath was used for, but since later Indian culture placed a huge emphasis on ritual purity, which is the basis for the caste system, some historians have speculated that the bath might have been like a giant baptismal pool.
