Built in the late 19th century, Haus Fühlingen has a long, violent history — from rumored suicides and murders to its use as a Gestapo outpost during WWII. Locals report apparitions in the windows, footsteps in empty corridors, and phantom screams from the basement. Ghost hunters have recorded EVP voices and sudden temperature drops. Abandoned for years, the mansion is now considered one of Germany’s most haunted properties.
