Julia Hasdeu Castle in Câmpina, Romania, is haunted by Julia’s spirit, but in harmless ways. Even today museum staff notice her presence.
Julia’s spirit peered through this hole in the thick wall to communicate with her father. He constructed the castle after her death according to her instructions. She had only lived 18 years.
I peeked through the circle into the spiritualism room where Julia’s communication had been recorded by cultured mediums using automatic writing directed by Julia to her father.
