Marvel at the size of Cathedral of Romualdo Museum. Schedule in a mass if you can or just take a seat and enjoy the peace and quiet.
When you've spent a bit of time at this principal church in Centro Storico, why not check out Lama Monachile Beach, Cala Paura Beach, and Grotta Ardito Promenade? They're not too far from Cathedral of Romualdo Museum and also a hit with many travelers.
