On March 21, 1963, USP Alcatraz closed after 29 years of operation. It did not close because of the disappearance of Morris and the Anglins (the decision to close the prison was made long before the three disappeared), but because the institution was too expensive to continue operating.

Why was it so expensive to run Alcatraz?

Primarily because of rising costs and deteriorating facilities. Operationally, Alcatraz was the most expensive prison of any state or federal institution. It was determined that other institutions could serve the same purpose for less cost.

Who owns Alcatraz now?

It is one of San Francisco's major tourist attractions, attracting some 1.5 million visitors annually. Now operated by the National Park Service's Golden Gate National Recreation Area, the former prison is being restored and maintained.
