Alcatraz is an iconic island in San Francisco Bay, famously known as a formidable federal penitentiary. Its isolated location, surrounded by cold, strong currents, made it an virtually inescapable prison that housed some of America's most notorious criminals.
Initially a crucial military fortification protecting San Francisco Bay's vital commerce, Alcatraz's complex engineering was later repurposed for a maximum-security prison. It holds profound social historical significance as a symbol of federal justice and punishment, drawing millions today as a major tourist attraction.
