Prague's Astronomical Clock Alphonse Mucha is the most famous artist to come out of the Czech Republic. He even designed their currency when Czech became a free country.
Kostnice was a normal cemetary until the Plague hit. It was then innendated with bodies, about 15,000 of them. For reasons unknown, a half-blind monk started making these elaborate sculptures out of their bones. It is a pretty incredible sight. This chandelier contains every bone in the human body.
