The Tiber River, Rome’s lifeline, holds immense historical and cultural significance. It flows through the city, forming the Isola Tiberina and serving as a symbol of Rome’s founding. Tributaries like the Aniene and Marrana rivers add to its grandeur, while bridges such as Ponte Sant’Angelo connect its banks. Notable landmarks include Ripa Grande and the mythical associations of Romulus and Remus, Julius Caesar, and Augustus. Environmental concerns and management efforts prioritize water quality and conservation.
