Angel Island is an island in San Francisco Bay offering expansive 360° views of the San Francisco skyline, the Marin County Headlands and Mount Tamalpais.
The entire island is included within Angel Island State Park and is administered by California State Parks.
The island, a California Historical Landmark, has been used for a variety of purposes, including military forts, a US Public Health Service Quarantine Station, and a US Bureau of Immigration inspection and detention facility.
The Angel Island Immigration Station on the northeast corner of the island, where officials detained, inspected, and examined approximately one million immigrants, has been designated a National Historic Landmark.
Escape from Alcatraz tells the story of the only three men ever to escape from the infamous maximum security prison at Alcatraz. In 29 years, the seemingly impenetrable federal penitentiary, which housed Al Capone and "Birdman" Robert Stroud, was only broken once - by three men never heard of again.
