The City was divided into two sections:
1. The Citadel.
2. The Lower Town.
The Citadel (Fortress):
This is built On a man made platform. It is on the western side of the city. This is the highest part of the city. There are two reasons for its height. Firstly, it is built on higher ground. Secondly, the buildings are put up on a platform made of clay bricks. The fortress is protected with walls around it. Therefore it looks different from the Lower Town. In the fortress, there are tall buildings. They are public buildings. They were used for special public activities. The Warehouse and the Great Bath were the main structures in the fortress.
The Warehouse:
The biggest building in Mohenjo Daro is the Warehouse there. The bottom part of the Warehouse is made of bricks. They still remain there. The upper part was built with wood. It got destroyed long ago. The Warehouse was used to store the left over grain.
