From riots and escape attempts to inmate baseball leagues and a prison band featuring Al Capone, these behind-the-scenes photos reveal what life was really like at Alcatraz.

Although it has been closed since 1963, Alcatraz is still one of the most notorious penitentiaries in American history. But before “the Rock” was a maximum security prison, the island off the coast of San Francisco was a military fort. And today, it’s a popular tourist destination. Indeed, photos of Alcatraz Island over the decades show just how much the landmark has changed since it was first developed.

As a prison, Alcatraz was designed to be escape-proof, though some men still tried to flee. Since it was located on an isolated island in San Francisco Bay, however, even those who managed to escape the walls of the penitentiary itself were more than likely doomed to meet an ill fate in the icy waters below. In theory, most prisons are meant to rehabilitate inmates. Alcatraz was different. It had one goal and one goal only: containment.

Eventually, the operation and maintenance costs for the crumbling facility simply rose too high to keep the prison open. The final inmates were transferred out in March 1963, 29 years after the first federal prisoners arrived.

In 1969, Native American activists began occupying the island to protest government policies, remaining for nearly two years. Then, in 1972, the National Park Service purchased the land, and it's been open to tourists since October 1973.

Above, look through 55 photos of Alcatraz Island that reveal what life was like there over the years. And below, read more about its fascinating — and turbulent — history.

From Military Fortress To Inescapable Prison

Long before Alcatraz was a massive holding cell for America's most hardened gangsters, it was nothing more than an island off the coast of a landmass that would become the United States.

It was first mapped in 1775 by the Spanish explorer Juan Manuel de Ayala, who dubbed it La Isla de los Alcatraces, or "The Island of the Pelicans." That name was eventually anglicized to Alcatraz, which it remains known as to this day.

In 1850, a presidential order marked Alcatraz as a potential future location for a U.S. military site. After the gold rush transformed San Francisco into a bustling port city, the strategic position of Alcatraz was made abundantly clear, and fortifications such as cannons and ramparts were built on the island — as well as the West Coast's first lighthouse.

At the same time, a secondary use for Alcatraz also emerged: confinement.

As early as the Civil War, military prisoners were being sent to the remote outpost. Despite being heavily fortified for war, the cannons on Alcatraz were never fired in battle, and over time, its use as a confinement facility overtook its role as a strategic fort. By 1907, Alcatraz was officially designated a military prison.

Over the following decades, inmates helped build many of the structures that would later define the penitentiary, from cell blocks to watchtowers. Soldiers convicted of crimes such as desertion, mutiny, or insubordination worked in rock quarries and maintained the island under the Army's stern watch. Just over two decades later, however, a new chapter in Alcatraz's history began.

Iconic Photos Of Alcatraz Island During Its Federal Penitentiary Era

With organized crime on the rise and federal prisons struggling to contain high-profile gangsters, the Department of Justice took over Alcatraz in 1933. The island was transformed into a maximum security prison that was intended to break the spirits of those considered the most incorrigible. Surrounded by icy waters and deadly currents and reinforced with steel and concrete, Alcatraz became a place where escape was thought to be impossible.

When the first group of 137 federal prisoners arrived in August 1934, they stepped into a world of rigid control.

Silence was enforced in mess halls, letters were screened and censored, and privileges were stripped to the bare minimum. Each cell only measured about five by nine feet and was furnished with just a bed, sink, and toilet. Meals were plain but consistent, a deliberate policy to prevent hunger from sparking unrest. Punishment for rule-breaking was severe, and those sent to solitary confinement in the D-Block isolation wing called it "the Hole" due to how dark and bare the cells were.

"I killed an Army sergeant to protect my own life. I served 10 years in Atlanta Federal Penitentiary, which was bad enough, and two months in Alcatraz prison, which was worse," reads the account of inmate Bryan Conway, published originally by Reader's Digest in 1938.

"The first glimpse of Alcatraz prison fills a convict with grim forebodings," Conway said. "That bare rock rising out of San Francisco Bay has little vegetation. It is subject to fogs and damp winds. I've seen guards wearing overcoats in midsummer. I am certain that part of the convict's dread of Alcatraz prison is due to adroit propaganda regarding the terrors of 'the Rock.'"

Alcatraz typically held between 260 and 275 inmates at any given time, with a staff of around 90 guards, maintenance workers, clerics, mechanics, and administrators. Prisoners worked in laundries, workshops, and factories. They were permitted some recreation, including handball and baseball in the yard, and music under strict conditions. An inmate band even put on performances, but the monotony in combination with an ever-present sense of isolation took a psychological toll on both the prisoners and the guards.

"Men go slowly insane under the exquisite torture of restricted and undeviating routine," said Conway. "And not so slowly at that, because out of a total of 317 prisoners, 14 went violently insane during my last year on the Rock, and any number of others were what we call 'stir crazy,' going about their familiar routine like punch-drunk boxers."

Unlike most penitentiaries, Alcatraz was also home to a community of prison staff and their families. Photos of Alcatraz Island from this period show their separate housing on the island, as well as a school, a chapel, and even a small grocery store for guards' children and spouses. This community existed in stark contrast to the strict prison regime at the heart of the island, contributing to the enduring fascination with the island's past.

It wasn't the only thing that cemented Alcatraz's place in history, though.

Infamous Inmates And Escape Attempts

A large part of Alcatraz's notoriety came from the caliber of men it held. And over the 29 years it was in operation, Alcatraz saw some infamous inmates.

Chicago mob boss Al Capone, stripped of his influence and weakened by syphilis, spent four-and-a-half years on the island, even playing banjo in the prison band. By then, Capone had become unpopular among his fellow inmates, simultaneously asking for the respect he had once earned and too weak to demand it.

"Capone gets lonesome because he doesn't come in contact with many other men," Conway recalled. "He has lost weight, is said to be in mortal fear for his life, and is deprived of all the privileges he used to purchase at Atlanta."

George "Machine Gun" Kelly, once a feared kidnapper, meanwhile, became a model prisoner and was mockingly called "Pop Gun Kelly" by his fellow inmates.

Alvin "Creepy" Karpis, a notorious kidnapper and bank robber, served the longest sentence of any Alcatraz prisoner: 26 years.

Another member of the same gang, Arthur "Doc" Barker, was killed during an escape attempt in 1939. Despite this, Barker was hardly the only person to ever make an attempt to flee the prison.

Between 1934 and 1963, 36 men attempted to flee in 14 separate incidents. Most were caught, killed, or presumed drowned, but a few cases remain unresolved. In 1937, for instance, Theodore Cole and Ralph Roe vanished into the bay after escaping through a window in the prison's rubber mat shop. They were never seen again. Authorities assumed they drowned, but some speculated they may have survived.

Then, in 1946, the so-called "Battle of Alcatraz" erupted when six inmates, led by Bernard Coy, managed to overpower guards and seize weapons. Their bid for freedom failed when they could not access the prison yard, but the standoff lasted two days. U.S. Marines were called in. Photos of Alcatraz Island during the siege show plumes of smoke emerging from the prison — and by the time it cleared, two guards and three inmates were dead.

The most famous escape attempt, however, came in June 1962, when Frank Morris and brothers John and Clarence Anglin executed a bold and daring plan. Using handmade tools, they carved through the walls of their cells, created papier-mâché heads to fool guards, and escaped into the bay on a raft fashioned from raincoats. The FBI concluded they drowned, but evidence and family claims have long fueled speculation that the men actually made it to freedom.

Alcatraz Island's Reopening As A National Park

In either case, the men's success in their endeavor — at least, in making it off the island — was indicative of a larger breakdown of Alcatraz's security. By the late 1950s, the prison buildings had begun to crumble. Salt water and wind eroded the concrete, plumbing rusted, and the cost of operation far outstripped that of other prisons, especially since every supply had to be shipped in.

At one point, it cost more than three times as much to house a prisoner on Alcatraz Island as it did on the mainland.

With all this in mind, Attorney General Robert F. Kennedy ordered the prison closed in 1963. On March 21, the final group of inmates was transferred, and the doors of Alcatraz Federal Penitentiary closed for good. That didn't mark the end of the island's story, however.

Occupation Of Alcatraz

In 1969, Native American activists occupied Alcatraz for 19 months, invoking a treaty that allowed indigenous groups to reclaim unused federal land. The protest brought national attention to Native rights before the government forcibly ended it in 1971, after the Nixon administration concluded that no agreement could be reached.

A year later, Alcatraz was incorporated into the Golden Gate National Recreation Area. Today, the National Park Service manages it as a historic site. Over a million visitors now walk through its decaying cell blocks each year, listening to audio tours that include the voices of former inmates and guards.
