Saints Peter & Paul Basilica

This guide to Saints Peter & Paul Basilica in Prague opens with a legend: a priest bet the devil he could finish Mass faster than the devil could fly to Rome and back with a stone column, dragged the prayers out, and watched the devil hurl the broken column down the hill in fury. You'll hear how those fragments sat inside the church for centuries as proof of the story, and what geologists later found when they tested the stone. A strange inscription on one piece has never been deciphered.
