Not a villa but a small city of pleasure, built by the emperor Hadrian near Tivoli in the 2nd century AD. Hadrian, who travelled the whole empire, recreated the places he loved here: an Egyptian canal, a Greek portico, baths, libraries, theatres, spread across acres of grounds. The Canopus, a long pool lined with columns and statues, is the postcard image. Later popes and cardinals looted its marbles for their own villas nearby. Even as a ruin it is the most sophisticated Roman residence ever built, an emperor's memory palace in stone.
