After I had visited the dockyard thoroughly, I walked towards the main town of the city. Harappan cities are mainly divided into three parts: upper town, middle town and lower town. On the upper town, we find the acropolis or the citadel. In the middle town, people with upper category (like ministers and traders ) used to live and in the lower town, farmers, coppersmith etc used to live. Although Lothal is not a big site like Harappa or Dholavira, it still gives a great hint of the town planning of that era.
(Harrapa and MohenJodaro people might not aware of the floods) Lothal people were definitely aware of the floods of Sabarmati river as they had developed well planned city which could withstand the floods to a great extent. They created sun dried brick walls around the city. Walls in the upper town were built with fire dried or sun dried brick and in the lower town were built with the mud bricks.
I walked towards the warehouse where the beads and gems to be exported were packaged and sealed. It is supposed that the warehouse was divided into 64 blocks. 12 blocks are still visible.
