Alcatraz Penitentiary is located in California in San Francisco.
It became a Federal Penitentiary about eighty years ago.
Alcatraz was the prison where Al Capone was sent.
He wasn't happy about the place where he went.
Alcatraz had four wardens, they were James Johnston, Edwin Swope, Paul Madigan and Olin Blackwell.
Machine Gun Kelly, Mickey Cohen, Robert F. Stroud and many other criminals were sent to this jail.
Alcatraz is located on an island and was believed to be escape proof.
But in 1962, three men may have shown us that that wasn't the truth.
They escaped but were presumed dead but it's possible that they survived.
Their bodies were never found, nobody knows for sure if they're still alive.
Alcatraz closed in 1963 because of high maintenance costs and a poor reputation.
This wasn't a good prison to be sent to, believe me that's no exaggeration.
