Rome is in the Lazio region of central Italy on the Tiber river (Italian: Tevere). The original settlement developed on hills that faced onto a ford beside the Tiber island, the only natural ford of the river. The historic centre of Rome was built on seven hills: the Aventine Hill, the Caelian Hill, the Capitoline Hill, the Esquiline Hill, the Palatine Hill, the Quirinal Hill, and the Viminal Hill. The city is also crossed by another river the Aniene which joins the Tiber north of the historic centre.

Although the city centre is about 24 km (14.9 mi) inland from the Tyrrhenian Sea, the city territory extends to the shore, where the south-western district of Ostia is located. The altitude of the central part of Rome ranges from 13 m (43 ft) above sea level (at the base of the Pantheon) to 139 m (456 ft) above sea level (the peak of Monte Mario).[12] The Commune of Rome covers an overall area of about 1,285 km2 (496 sq mi), including many green areas.

Throughout the history of Rome, the urban limits of the city were considered to be the area within the city walls. Originally, these consisted of the Servian Wall, which was built twelve years after the Gaulish sack of the city in 390 BC. This contained most of the Esquiline and Caelian hills, as well as the whole of the other five. Rome outgrew the Servian Wall, but no more walls were constructed until almost 700 years later, when, in 270 AD, Emperor Aurelian began building the Aurelian Walls. These were almost 19 km (12 mi) long, and were still the walls the troops of the Kingdom of Italy had to breach to enter the city in 1870. Modern Romans frequently consider the city's urban area to be delimited by its ring-road, the Grande Raccordo Anulare, which circles the city centre at a distance of about 10 km.
