The Aqua Claudia was an ancient Roman aqueduct that supplied water to the city of Rome. Completed in 52 AD during the reign of Emperor Claudius, it was known for its impressive length of about 69 kilometers (43 miles) and its elegant arches. The aqueduct drew water from springs near the Anio River, ensuring a steady supply for public baths, fountains, and private households. Constructed primarily of concrete and stone, the Aqua Claudia featured striking elevated sections that showcased Roman engineering skills. It was part of a larger network of aqueducts, including the Aqua Anio Novus, which together helped sustain the growing population of Rome.
