Rome is a city famous for its numerous fountains, built-in all different styles, from Classical and Medieval, to Baroque and Neoclassical. The city has had fountains for more than two thousand years, and they have provided drinking water and decorated the piazzas of Rome. During the Roman Empire, in 98 AD, according to Sextus Julius Frontinus, the Roman consul who was named ''curator aquarum'' or guardian of the water of the city, Rome had nine aqueducts which fed 39 monumental fountains and 591 public basins, not counting the water supplied to the Imperial household, baths, and owners of private villas. Each of the major fountains was connected to two different aqueducts, in case one was shut down for service.
