Historical Attractions That Are Actually Kind of Creepy

19. The Dark Secrets of the Sedlec Ossuary (Czech Republic)

Also known as the "Bone Church," the Sedlec Ossuary in Kutná Hora, Czech Republic, is an unsettling yet strangely beautiful site. The interior is decorated with the bones of over 40,000 people, arranged into intricate designs, chandeliers, and sculptures. These remains belong to victims of the Black Plague and the Hussite Wars. Walking through the church, it's impossible not to feel the weight of history pressing down. While it is meant as a place of reverence, there is something undeniably eerie about being surrounded by so many human remains, each one a silent witness to history.
