A small but unmistakably Renaissance palace squeezed into the medieval centre, opposite the Duomo. Federico da Montefeltro built it on the site of an older Lombard palace in the 1470s. The pretty inner courtyard, with its red brick and white travertine, is the highlight. The famous studiolo — a tiny private study covered in dazzling wooden marquetry of trompe-l'œil shelves — was sold to the Metropolitan Museum in New York in 1939; what you see in the original room is a reconstruction. Still worth visiting for the rest of the palace and the courtyard.
Combined ticket with the Civic Museum.
