The Rubicon is a shallow river in northeastern Italy, just south of Cesena and north of Rimini. It was known as Fiumicino until 1933, when it was identified with the ancient river Rubicon, crossed by Julius Caesar in 49 BC. The river flows for around 80 km (50 mi) from the Apennine Mountains to the Adriatic Sea through the south of the Emilia-Romagna region, between the towns of Rimini and Cesena.
