Rome is in the Lazio region of Central Italy at the confluence of the Aniene and Tiber (Italian: Tevere) rivers. Although the city center is about 24 kilometers inland from the Tyrrhenian Sea, the city territory extends to the very shore, where the south-western Ostia district is located. The altitude of the central part of Rome ranges from 13 m (43 ft) above sea level (in Piazza del Popolo) to 120 m (394 ft) above sea level (the peak of Monte Mario).[citation needed] The comune of Rome covers an overall area of about 1,285 km² (496 sq mi), including many green areas.
