The cities of Ancient Egypt and Mesopotamia were formed mainly along large rivers. Since the rivers were overflowing, people built houses on the hills, which they often built themselves. The main material was adobe brick. There was little space on the hill, so houses were built close to each other, and the streets were narrow and crooked. There were no sewers, and the slop was simply poured into the street.
In the ancient city of Mohenjo-Daro, which arose at about the same time as the first cities of Egypt and Mesopotamia, houses and streets were built according to a preliminary plan. The width of the streets reached 10 meters. There was a water supply and sewerage system. The buildings were built from baked bricks.
