Tomb of St. John of Neponuk

Lavish tomb constructed in solid silver, and draped in red velvet.
Crazy story involving something about a vicious murder, being bound
and thrown off the St. Chatles bridge. Later, his saintly remains were
exhumed, and his "tongue", the only remaining flesh, was put into the
tomb (which was later proven be his brain matter. Eeeewwwwweee).
