1933: The Rock Becomes a Fortress: the U.S. Government Claims Alcatraz Island

The U.S. Department of Justice announced the acquisition of the military facility on Alcatraz Island on this day in 1933, marking the start of its transformation into a federal maximum-security penitentiary. It would be nearly a year before the island was formally designated a federal prison and the first inmates arrived.

Alcatraz was built for one purpose: to hold prisoners who had proven too disruptive, too dangerous, or too likely to escape from every other federal institution. Surrounded by cold currents and strict discipline, it would soon house names like Al Capone and Robert Stroud, cementing its reputation as America’s most feared prison.
