The Amityville House, located at 112 Ocean Avenue in Amityville, New York, is infamous for the 1974 mass murder of the DeFeo family, when Ronald DeFeo Jr. shot and killed his parents and four siblings. A year later, the Lutz family moved in but fled after just 28 days, claiming they experienced terrifying paranormal activity, including ghostly voices, levitation, and demonic visions. Their story inspired The Amityville Horror book and movie franchise, though many believe it was a hoax. Despite skepticism, the house remains one of the most famous haunted locations in pop culture.
