A look inside Alcatraz, the world’s most famous prison

On August 11, 1934 (90 years ago), a barge transporting 32 of America’s most dangerous criminals docked at the Alcatraz Federal Penitentiary. They were its first prisoners. Nicknamed “The Rock,” the prison was built on a 22-acre outcrop 1.5 miles offshore in San Francisco Bay’s cold, turbulent, shark-infested waters. It was deemed unescapable. By the time Alcatraz closed in 1963, there had been 14 escape attempts involving 36 inmates. One group of three succeeded but were never found. Here’s a look at the world’s most famous prison.

ON THE ISLAND

Alcatraz held roughly 1,576 prisoners from 1934 to 1963, with an average population of 260 to 270. Its maximum capacity of 336 was never reached. Many of the prison staff lived on the island with their families.

THE GREAT ESCAPE

In 1962, three inmates managed to break out of Alcatraz. However, no evidence of their survival was ever confirmed. Here’s how they did it:

The three men carved an opening in the wall of their cell with metal spoons. On the night of their escape, masks made of papier-mache and human hair were placed on their pillows to make it look like they were asleep in bed.
The three crawled through the opening and made their way along a corridor behind the walls and climbed out a ventilator on the roof.
They slid down the bakery smokestack at the rear of the cell house.
They climbed over a fence and dashed to the northeastern shore of the island, where they launched a raft made of 50 stolen raincoats

INSIDE THE PRISON

The prison building was built between 1910 and 1912, when Alcatraz was a military facility. When the disciplinary barracks were transferred from military control to the Bureau of Prisons in 1933, the building was renovated at a cost of $260,000 into a cell house with four cell blocks and reinforced cell bars to prevent escapes. There were 336 cells in B and C blocks.

THE CELL

Cells had a small sink with cold running water, a small sleeping cot and a toilet. Most men could extend their arms and touch each wall within their cell.
