The interior of this gorgeous 16th-century villa is fantastically frescoed from top to bottom. Several paintings in the Loggia of Cupid and Psyche and the Loggia of Galatea, both on the ground floor, are attributed to Raphael. On the 1st floor, Peruzzi’s dazzling frescoes in the Salone delle Prospettive are a superb illusionary perspective of a colonnade and panorama of 16th-century Rome.
English-language guided tours depart at noon on Saturday. On the 2nd Sunday of each month, there's an atmospheric guided tour (in Italian), accompanied by musicians playing Renaissance music; reservations are required.
