43 Creepiest Locations Around The World To Be Actually Used In Film

19. Moosham Castle, Austria – The Cursed Fortress of Witch Trials and Werewolf Legends

Deep in the misty Austrian Alps, Moosham Castle looms like something straight out of a Gothic horror novel—because it practically is. Used as a filming location for the 1971 cult horror film Mark of the Devil, this medieval fortress has a history even darker than the films it inspired. Built in the 13th century, Moosham Castle became infamous during the Salzburg Witch Trials of the 17th century, one of the deadliest witch hunts in European history. Hundreds of people—mostly women—were accused of witchcraft, tortured, and executed within its walls, leaving behind an aura of suffering and unrest that lingers to this day. But the castle’s horrors don’t end there. Moosham is also known as “The Werewolf Castle” due to reports of strange animal attacks and bizarre deaths in the surrounding forests during the 18th century. Villagers believed werewolves lurked in the shadows, and many suspected individuals were imprisoned in the castle’s dungeons, left to die in chains. These real-life horrors made Moosham the perfect filming location for Mark of the Devil, an exploitation horror film infamous for its brutal depictions of medieval torture and witch trials. The film’s production only added to the castle’s unsettling legend—cast and crew members reported unexplained phenomena, including eerie whispers, sudden temperature drops, and objects moving on their own. Some even claimed to see shadowy figures lurking in the dungeons where real prisoners once suffered.
