During excavating several sites, our architects learnt about the ancient architecture and skills of people in those days. In ancient time, the towns were divided into three sections:
- Fort of rulers (Citadel)
- Houses of administrative officers situated on the upper part of town
- Residences of common people situated on the lower part of town.
upper part of town (3) Residences of common people situated in the lower part of town. Upper part of the town was elevated and safe with double-storeyed houses having two to five rooms. Houses on the lower part of the town were single-storeyed mainly constructed with hand-made bricks. Roads in the towns were straight and long, intersecting one another at right angles. The roads were wide enough for a number of vehicles to pass at a time. People of Indus Valley Civilization had developed many more beautiful and systematic towns compared to other civilizations of the world from the architectural point of view.
