If you're afraid of haunted places, this church is probably worth avoiding. The inside of this historical Christian building near Prague is covered in the remains of over 40,000 people. The matter in which it's done is quite extraordinary as they've managed to create some elaborate works of art including chandeliers and bells, all out of bones.
The Sedlec Ossuary, also referred to as Kostnice, contains thousands of human bones. The town of Sedlic is pretty ordinary otherwise; it's not filled with creepy worshipers of dark practices.
