Answers
Many of these cities were divided into two or more parts. Usually, the part to the west was smaller but higher. Archaeologists describe this as the citadel. Generally, the part to the east was larger but lower. This is called the lower town. Very often walls of baked brick were built around each part. The bricks were so well made that they have lasted for thousands of years. The bricks were laid in an interlocking pattern and that made the walls strong., each drain had a gentle slope so that water could flow through it. Very often, drains in houses were connected to those on the streets and smaller drains led into bigger ones. As the drains were covered, inspection holes were provided at intervals to clean them.
