Take Mohenjo-Daro in ancient India—it had an advanced drainage system and grid-like streets 4,500 years ago! Or the Mayan city of Tikal, with its towering pyramids and complex water management systems hidden deep in the jungle. Angkor in Cambodia was another mind-blower—it was the largest pre-industrial city, with an incredible network of canals and reservoirs. These places were bustling hubs of innovation, culture, and trade, long before modern cities were a thing. It’s amazing to think how advanced they were, only for many to vanish under the sands of time! Learn more about your ad choices.
