Paranormal reports at Alcatraz Island

Alcatraz Island, the former federal penitentiary, has been the subject of numerous anecdotal reports of unexplained sounds, voices, and cold spots from visitors, tour guides, and former staff. Accounts include hearing voices and piano music in the cell blocks and unusual sensory experiences in the Warden's House and cellhouse. These stories are widely circulated in books, documentaries, and visitor testimonials and are a prominent part of the island's public history and tourism narrative. The accounts are anecdotal and not scientifically verified.
