Alcatraz
"The Rock" as others know! Alcatraz is an island situated near the bay of San Francisco, from the bay it can be seen like a big rock in the middle of the gulf in San Francisco, this is why they call it simply “The Rock”. The history starts in 1775 when a Spanish explorer found and named it “Isla de los Alcatraces” which means The Island of the Lost Pelicans. For years, the island wasn’t approached by anybody because of the bizarre place. After the Americans spread all around America, the military decided to make a military fortress to protect the San Francisco Bay by invaders, because of the lately discovered gold field which was one of the biggest which was discover in that time.
Less than two years later, the Civil War broke out, and Alcatraz was considered an important Union defense place against the Confederate army. Although a military base remained in use on the island until 1933, Alcatraz was never actually attacked. For much of that time, the island served as a military prison more than as a defensive outpost. The year after the military left, the Bureau of Prisons began using the island as a maximum-security prison. One of its first inmates was Al Capone who was the biggest gangster head in the 1920s. So Alcatraz is in deed was the famous prison of North America, with a place where security was the sky and no one could escape from the place because of the big waves which made difficult to swim.
But, there were some prisoners who managed to escape but some of them couldn’t got of the coast, others have probably drown in the water, some of them who were got swimmers and could get to the bay but they were captured in days. Another legendary prisoner, Robert Stroud, was known as the Birdman of Alcatraz. Stroud had studied canaries while he was in prison at Leavenworth before being transferred to Alcatraz and he had even published a book on canary physiology and disease. But during his 17 years at Alcatraz, he was never permitted to study birds getting the nickname Birdman. He wasn’t even permitted to see the 1963 film Birdman of Alcatraz, for which actor Burt Lancaster won an Oscar. In 1963 the prison was closed because of the place didn’t met the orders. From 1963 till 1669 it was closed, in 1669 100 Native Americans protesters used it for 19 moths for protested for the island, but the Government didn’t gave it to them. Today tourists come to see Alcatraz, the little island out in San Francisco Bay that was once a federal penitentiary.
