President Trump orders federal agencies to reopen Alcatraz

US President Donald Trump says he is ordering federal agencies to rebuild and reopen Alcatraz — the notorious maximum security prison that closed more than 60 years ago.

"I am directing the Bureau of Prisons, together with the Department of Justice, FBI, and Homeland Security, to reopen a substantially enlarged and rebuilt ALCATRAZ, to house America's most ruthless and violent Offenders," Trump said in a post on Truth Social.

The historic former U.S. Penitentiary Alcatraz, opened in 1934, is widely known as The Rock.

Its buildings dominate the craggy landscape of Alcatraz Island, which lies about 1.5 miles north of San Francisco's famed Fisherman's Wharf.

Alcatraz once housed dangerous criminals such as the infamous mobster Al Capone, under an incarceration strategy that sought to concentrate difficult prisoners in one facility, segregating them from less dangerous inmates in the prison system.

Trump's message suggests he wants to restore Alcatraz to its original dual purpose.

The twin goals for building the original prison, according to the Federal Bureau of Prisons, were "to deal with the most incorrigible inmates in Federal prisons, and to show the law-abiding public that the Federal Government was serious" about stopping rampant crime in the 1920s and 1930s."

"REBUILD, AND OPEN ALCATRAZ!" the president said on Truth Social. He added later in his message, "The reopening of ALCATRAZ will serve as a symbol of Law, Order, and JUSTICE."

Trump did not provide details about a timeline for reopening the prison. The National Park Service did not reply to NPR's request for comment about the president's new plan for Alcatraz before this story published.

But enacting Trump's proposal would come with a steep price tag, both for constructing and operating a new prison facility on an island whose most plentiful natural resource is sandstone.

Alcatraz was shuttered "because the institution was too expensive to continue operating," according to the Federal Bureau of Prisons.

It said operating the island prison was nearly three times more expensive than any other federal prison at the time.

"This isolation meant that everything (food, supplies, water, fuel...) had to be brought to Alcatraz by boat," the bureau says.

"For example, the island had no source of fresh water, so nearly one million gallons of water had to be barged to the island each week."

Then-U.S. Attorney General Robert F. Kennedy closed the federal penitentiary in 1963.

Alcatraz is currently a museum administered by the National Park Service, as part of the Golden Gate National Recreation Area since 1972.

Placing the prison in historical context, the NPS says it "represents the federal government's response to post-Prohibition, post-Depression America. Both the institution and the men confined within its walls reflect our society during this era."
