Historical Attractions That Are Actually Kind of Creepy

23. The Lost Souls of the Houska Castle (Czech Republic)

Houska Castle, located in the Czech Republic, was built for a peculiar reason: to seal off what many believed was a literal "gateway to Hell." Legends tell of dark, winged creatures emerging from a deep hole in the ground, terrorizing the locals. The castle was constructed over this supposed entrance, with no fortifications, no water source, and no strategic value—its sole purpose seemingly to keep something inside. Paranormal activity is frequently reported within the castle walls, and visitors describe an oppressive, chilling energy. Whether the legends are true or not, Houska Castle remains one of the strangest and most unnerving historical sites in Europe.
