Alcatraz Island the high-security prison which existed from 1934 to 1963,
also commonly referred to as Alcatrazi s located in the San Francisco Bay,
1.5 miles (2.4 km) offshore from San Francisco, California, United States.
Often referred to as “The Rock”, the small island was developed with
facilities for a lighthouse, a military fortification, a military prison (1868), and a federal prison from 1933 until 1963.
Beginning in November 1969, the island was occupied for more than 19
months by a group of Aboriginal peoples from San Francisco who were part
of a wave of Native activism across the nation with public protests through the 1970s. In 1972, Alcatraz became a national recreation area and received designation as a National Historic Landmark in 1986.
Today, the island’s facilities are managed by the National Park Service as
part of the Golden Gate National Recreation Area; it is open to tours. Visitors
can reach the island by ferry ride from Pier 33, near Fisherman’s Wharf, San
Francisco. Hornblower Cruises and Events, operating under the name
Alcatraz Cruises, is the official ferry provider to and from the island.
Hornblower launched the nation’s first hybrid propulsion ferry in 2008, the
Hornblower Hybrid, which now serves the island, docking at the Alcatraz Wharf.
It is home to the abandoned prison, the site of the oldest operating
lighthouse on the West Coast of the United States, early military fortifications, and natural features such as rock pools and a seabird colony (mostly Western Gulls, cormorants, and egrets).
According to a 1971 documentary on the History of Alcatraz, the island measures 1,675 feet (511 m) by 590 feet (180 m) and is 135 feet (41 m) at highest point during mean tide. However, the total area of the island is reported to be 22 acres Landmarks on the island include the Main Cellhouse, Dining Hall, Library, Lighthouse, the ruins of the Warden’s House and Officers Club, Parade Grounds, Building 64, Water Tower, New Industries Building, Model Industries Building, and the Recreation Yard.
