ROME, Italy (AP) — Every year, millions visit Rome’s famous sites, but few enter the exclusive Colonna Palace.
This private home-museum, spread across four wings over an entire block in the city center, opens only to small groups for a few hours on Friday and Saturday mornings. The palace, owned by the Colonna family since the 12th century, houses paintings, sculptures and a 76-meter (249-foot) Great Hall.
