Ancient aqueducts were remarkable engineering structures built to transport water from distant sources to cities and agricultural areas. The most famous examples, like those in Rome, utilized gravity to move water through a series of channels, bridges, and tunnels. These systems allowed for a reliable water supply, which was essential for drinking, bathing, and irrigation. The construction of aqueducts dates back to ancient civilizations, including the Romans, Greeks, and Persians. They often featured arches and were made from materials like stone, brick, and concrete. The ingenuity of these structures laid the foundation for modern water supply systems, showcasing the importance of water management in urban planning.
