If it’s your first trip to Rome, you’ll probably walk past this without realising you can go up for incredible panoramic views. It’s huge and often called the “wedding cake” by locals because of its white marble. The rooftop elevator is worth doing for a quick skyline view if you don’t want another dome climb. Great stop between the Forum and Piazza Venezia.

Opening Time: Approx 9:30am–7:30pm

How much time: 20–40 mins (longer if rooftop)

Best time: Late afternoon for light + views

Tip: Elevator to the top is paid but worth it for photos.
