I just finished watching the DVD set of Long Way Round, the documentary series of Ewan McGregor and Charlie Boorman's overland motorbike trip from London to New York (via, like, the entire Asian continent). Early in their journey they stopped in at the Sedlec Ossuary - a.k.a. The Bone Church in Kutná Hora, Czech Republic. The church is decorated (and I use the word loosely) with human skulls and bones. So you'll have a chandelier made of spinal columns, and walls made of skulls, and various similar ornamentations.
It's very, very weird. Interesting story behind it though. Take a look at Wikipedia. Gives me the heebs.
It got me to thinking, though, about the orthodox Christian fascination with relics: the bones of dead saints. Curious Expeditions has a whole collection of them, including the mummified skull of Saint Catherine, the petrified finger of Galileo (who wasn't even a holy man!), and similar delights. There's a (very funny) legend doing the rounds of the Italian town that enjoys the blessings of housing Jesus's foreskin.
That's possibly taking things a bit too far, I reckon.
