It is puzzling why most travelers miss a visit to this stunning Basilica, one of five papal ones in Rome. When talking to locals, we asked what their favorite place in the city may be, especially the ones travelers miss, and this Basilica was a top choice. Not only is it marvelous in terms of architecture and riches, but it is also home to the remains of Saint Paul, as well as the chains with which he was kept in captivity. The sheer grandiosity of the building, the amazing mosaic dome (that lights up if you contribute 1 euro) and the gold ceiling are a unique breathtaking experience not to be missed. It is just ten minutes by taxi, or five subway stops from the Colosseum.
