The Tiber River by fishandchips
Legend says Rome's founders, the twin brothers Romulus and Remus, were abandoned on the waters of the Tiber, where they were rescued by a she-wolf. Mythic king Tiberinus of Alba Longa was said to have drowned in the Albula river which resulted in the river being renamed the Tiber. Whatever really happened here, the Tiber is the 3rd longest in Italy and one of the main features of Rome. It's rather dirty to look at (it's full of silt apparently) but has been, historically, one of Rome main trade routes ending at Ostia where the port of the day was located.
