Power House, Utility building in Alcatraz Island, San Francisco, US
The Power House stands on the northwest coast of Alcatraz Island, featuring a white smokestack that extends into the San Francisco Bay skyline.
Built in 1939 for 186,000 dollars, the Power House formed part of a larger modernization project that included the water tower and New Industries Building.
The building represented industrial advancement on Alcatraz Island, marking the transition from military fortress to modern federal penitentiary infrastructure.
Between 1939 and 1963, this facility generated electricity for the entire island, including the federal prison, guard quarters, and administrative buildings.
The Power House tower contained specific security equipment: a Winchester rifle, a Colt pistol, gas grenades, and a gas mask for guard protection.
