Town Planning: The discovery of the Sumerian city of Ur has shed light on the lives of the early Mesopotamians. The Mesopotamian cities fell short in terms of town planning as compared to the Harappan centres but followed a uniform pattern nevertheless. The city was divided into three parts – the sacred area, the walled city on a mound and the outer town. The sacred area consisted of the temple tower or the ziggurat dedicated to the patron god of the city. There were also smaller temples of other gods. This area also had the storehouse as well as the offices. People resided in the walled city and the outer town areas. Houses were constructed along the streets, and each house had a central courtyard with rooms attached around it.
