Of all the Roman ruins that populate what is now a pleasant landscape of pine trees and meadows, under the distant gaze of the Alban Hills, the Villa of the Quintilii is perhaps the most impressive – almost a city in miniature, covering up to 24 hectares.

Lying on the ancient Appian Way as it runs south-east from Rome, the villa had its own theatre, an arena for chariot races and a baths complex with walls and floors lined in sumptuous marble.
