And Since I Am Dead, I Can Take Off My Head...

(Originally from Metafilter):

Walking down Zürich's Lindenhofstrasse, you might stop in surprise by a relief depicting two men and a woman, draped in gauzy robes, each one calmly carrying their own severed head. There is no explanatory sign. Don't worry, though: Felix, Regula and Exuperantius are just the city's cephalophoric patron saints.
