Sobre el lugar

Cold tidal currents made the federal penitentiary on Alcatraz an inescapable prison compound.

Juan Manuel de Ayala first mapped the island in the bay during Spanish exploration, mistaking the native birds for pelicans. By the middle of the nineteenth century, federal authorities fortified the rock with artillery batteries to safeguard coastal entries, while also erecting the earliest operational navigational beacon on the Pacific shoreline.

The compound shifted from a coastal citadel to a federal penitentiary designed for high-security detention. Escapes proved virtually impossible against freezing water temperatures and treacherous currents across the strait. Civilian authorities eventually shuttered the cellhouse, leaving the structures preserved for public transport access and historical tours.
