Lothal’s ancient dry-dock.
The statement “Dry-dock obtained from Lothal dates back to 2400 BC” is generally accepted by historians and archaeologists as accurate.
Lothal is an archaeological site located in the modern-day state of Gujarat, India. It was a prominent city in the ancient Indus Valley Civilization, which flourished in the region from around 2600 BC to 1900 BC.
The dry-dock at Lothal is a remarkable feat of engineering for its time. It was a large, rectangular structure, measuring approximately 227 meters by 11 meters, and was constructed using a sophisticated system of interlocking bricks and channels. The purpose of the dry-dock was to allow ships to be repaired or maintained without being beached on shore.
Archaeologists believe that the dry-dock at Lothal was in use between around 2400 BC and 1900 BC, making it one of the oldest known dry-docks in the world. Its discovery sheds light on the advanced level of engineering and maritime technology that existed in the ancient Indus Valley Civilization.
