Beneath the ominous penitentiary…in the ruins of an ancient fort…lies a maze of secret rooms and passageways still unexplored and unknown by the world. It's hard to believe, but much like the blockbuster movie "The Rock," the island of Alcatraz is riddled with underground rooms, tunnels, gunpowder, magazines, cisterns, and terrifying dungeons.  Come explore an even darker side of the world's most famous prison.
