Tiber River, Rome
Tiber River, Italian Fiume Tevere, historic river of Europe and the second longest Italian river after the Po. It is 252 mi (405 km) long.
Twisting in a generally southerly direction through a series of scenic gorges and broad valleys, the Tiber flows through the city of Rome and enters the Tyrrhenian Sea of the Mediterranean.
It doesn't seem to be as busy as the River Thames (London) or the River Seine ( Paris).
