Just a stone's throw from the bustling Piazza Navona, you'll find a true gem that many visitors miss: the Basilica di Sant'Andrea della Valle. Step inside and prepare to be amazed by the sheer scale and opulence of its Baroque interior. Your eyes will immediately be drawn upwards to the incredible frescoed dome, the second largest in all of Rome, which seems to open up to the heavens. It's a breathtaking space, rich with art and history, and even holds a special place in the hearts of opera lovers as the setting for the first act of Puccini's "Tosca". During the Christmas season this church displays several different Nativities.
