Ancient Roman aqueducts were impressive engineering structures built to transport water from distant sources into cities and towns. They utilized gravity to move water along a slight downward slope, often spanning valleys and hills. The aqueducts were made of stone, brick, and concrete, showcasing the advanced construction techniques of the Romans. These aqueducts supplied water for public baths, fountains, and private households, significantly improving urban life. Some of the most famous aqueducts, like the Pont du Gard in France and the Aqua Appia in Rome, still stand today, highlighting the ingenuity and durability of Roman engineering.
