Kalibangan, one of the key cities of the Seven Rivers Civilization, offers a fascinating glimpse into the building techniques used over 4,000 years ago. Located in present-day Rajasthan, this city is notable for its advanced use of fired bricks, a durable material that is a testament to the ingenuity of this ancient civilization.
The use of fired bricks
Fired bricks were made from clay and then hardened in specially designed kilns to withstand time and weather. These bricks were uniform in size, with standardized dimensions, which made them easier to assemble during construction. This shows impressive technical mastery and organization.
The layout of the houses
Kalibangan houses were generally rectangular, with rooms arranged around a central courtyard. This arrangement allowed for natural ventilation and provided a living space sheltered from the hot sun. The walls were built of carefully stacked fired bricks, sometimes covered with a protective coating.
A modular construction system
The people of Kalibangan used a modular construction method. The load-bearing walls were reinforced with well-aligned corners, ensuring the solidity of the whole. This system also made it possible to renovate or expand buildings without disturbing the overall structure.
An infrastructure designed to last
Houses were often built on raised platforms, probably to protect against flooding when nearby rivers rose. The streets were neatly aligned and followed a grid plan, reflecting an advanced urban organization.
An example of age-old know-how
Kalibangan’s building techniques show that the Seven Rivers Civilization was far ahead of its time. The use of fired bricks, combined with thoughtful planning, allowed these dwellings to last for centuries. This know-how continues to inspire researchers and is a testament to the civilization’s ability to adapt to its environment.
