St. Peter’s Basilica, Vatican City
Photograph by Kenneth Garrett
On the bones of St. Peter, tradition holds, the world's largest church took shape in the hands of Italy's great Renaissance and baroque artists. Bernini created the altar's towering bronze baldachin, along with much of the basilica's breathtaking decoration. The travertine-stone cathedral—mother church to all Roman Catholics—can hold 50,000 worshipers.

The City of Lights stretches out beneath one of Notre Dame's many gargoyles and chimeras. The difference? Gargoyles drain water away from the cathedral's facade, and chimeras are simple—though fantastic—decorations.
