In 19 BC, the ancient scholars wrote that with the help of a virgin, Roman technicians located a source of pure water only 14 miles (22 km) from the city.

It served Rome for hundred years, and you can't believe it ,but it serves Rome water supply still today.If you want to know more about Rome tours,visit  http://www.rome-tours.org
