A wonderful spot to enjoy a glowing Roman sunset, this piazza marks the summit of the Quirinale hill. The central obelisk was moved here from the Mausoleo di Augusto in 1786 and is flanked by 5.5m statues of Castor and Pollux reining in a couple of rearing horses.
If you’re in the neighbourhood on a Sunday you can catch the weekly changing of the guard (6pm in summer, 4pm the rest of the year).
