Villa in Via Colle Aurelia 1100

The cluster sits inside the built-up area of Rome, the national capital and a continuous urban municipality. The Tiber river runs through the city and the Aniene is a tributary on the north‑east side. The historic centre contains the Colosseum, the Roman Forum, the Palatine and St Peter's Basilica; the Historic Centre of Rome (together with properties of the Holy See and San Paolo fuori le Mura) is a UNESCO World Heritage Site. Vatican City is an independent state enclosed by the city. Large city parks and protected archaeological green corridors within the municipal area and under 15 km include Villa Borghese, Villa Ada and the Parco Regionale dell'Appia Antica (including the Parco degli Acquedotti and the Via Appia Antica). The Grande Raccordo Anulare orbital motorway runs roughly 10–15 km from the historic centre and frames the main metropolitan area. Roma Termini is the city's principal rail hub for long‑distance and regional services. Ciampino airport lies within the municipal territory to the south‑east and handles scheduled commercial flights; Leonardo da Vinci–Fiumicino airport is to the west of the city. The EUR district (south of the centre) contains 20th‑century institutional and office districts. The area is known for its concentration of ancient monuments, state institutions, museums and dense public transport connections.
