Spike Island: Unraveling the mysteries of ‘Ireland’s Alcatraz’
Original story by Katy Scott, CNN • Updated 20th September 2018
(CNN) — A star-shaped fortress atop a picturesque island off the southwest coast of Ireland once housed one of the world’s biggest prison populations.
While today Spike Island welcomes boatloads of tourists — much like Alcatraz in San Francisco Bay or Robben Island off the coast of South Africa — in Victorian times it was a place that many never left, with more than 1,000 prisoners dying there in less than four years.
In an attempt to learn more about the men who perished on this prison island, bioarchaeologist Barra O’Donnabhain began excavating the convict graveyard in 2013.
Over the past five years, O’Donnabhain and his team have uncovered some of the mysteries buried on Spike Island — including a grizzly procedure long ago carried out on dead prisoners’ corpses.
How an island became a prison
Spike Island — often described as “Ireland’s Alcatraz” — has a multilayered history.
Early records indicate the 104-acre island might have been a 6th-century monastic settlement. It gradually developed into a British military base in the 18th century, before it became a depot for convicts waiting to be shipped to Britain’s penal colonies, such as Australia and Bermuda.
“The prison was opened as a crisis response by the government to the Great Famine and to the perceived rise in criminality, because the court system at the time punished theft very harshly,” explains O’Donnabhain, an archaeology professor at University College Cork in Ireland.
From 1847, men and boys as young as 12 were sent to Spike Island, some for crimes that would today be considered trivial offenses, such as stealing potatoes.
‘Hell on Earth’
But by 1853 the number of prisoners on the island had risen to 2,500, making it possibly the biggest prison in the British Empire at the time, if not the world, in terms of the number of prisoners, according to O’Donnabhain.
Up to 40 prisoners were sardined in each dormitory-style room — measuring 40 feet by 18 feet — and there were no individual cells save for the punishment block, used to detain the most dangerous criminals.
A number of accounts from the time detail how solitary confinement in the prison’s punishment block was like “hell on Earth.” Over 1,000 prisoners died on the island and were buried in mass unmarked graves.
Various convict accounts from the punishment block detail how prisoners were heavily chained from wrist to ankle and severely broken from enduring what they described as “Hell on Earth.”
The prison’s draconian regime of forced labor coupled with poor living conditions and an inadequate diet meant convicts died almost daily in the early years, explains O’Donnabhain.
Digging up Spike
Records indicate that one of the island’s two graveyards, which O’Donnabhain hasn’t yet excavated, holds upwards of 1,000 prisoners who died before 1860.
O’Donnabhain and his team have excavated 35 burials from the other graveyard, which was used from 1860 onwards. By this point the number of deaths had drastically reduced to approximately one per month.
He says he was surprised by the element of care employed when prisoners buried their fellow inmates, particularly by how carefully they painted the cheap pine coffins to look like oak coffins.
“I read it as a gift from one prisoner to another,” says O’Donnabhain. “You’re being buried in a convict graveyard on a convict island that’s out of bounds to the rest of society, and yet your peers are just taking care to make a statement that this person was of some worth.”
Skulls for ‘science’?
But one of the most curious discoveries was that a handful of skeletons had the top of their skulls removed.
O’Donnabhain speculates that this might have been part of a wider study in the 1870s spearheaded by Italian scientist Cesare Lombroso to identify the characteristic physical features of the “born criminal.”
“Lombroso did a lot of autopsies of hanged criminals, and he found a particular variation in the architecture of the skull which he said is the sign of the ‘natural born criminal,'” explains O’Donnabhain.
Unsurprisingly, Lombroso’s theories have long been discredited.
But O’Donnabhain says he can’t be certain that that’s exactly what they were doing on Spike Island.
Writing’s on the wall
The prison housed convicts from 1847 to 1883. “There were a lot of prisoners who were there for things we would not regard as crime today, and sentenced to hard labor,” says historian Gillian O’Brien of Liverpool John Moores University.
When the 19th century prison closed in 1883, the island resumed its original function as a military barracks, only to re-open as a prison from 1985 to 2004.
When O’Donnabhain arrived nearly a decade later he says the sheets were literally still on the beds.
So, before he began excavating, his team documented the modern graffiti scrawled by 20th century prisoners.
“What really struck me in doing that work was the continuity between the Victorian prison and the modern prison,” says O’Donnabhain.
The graffiti on the walls detailed the prisoners’ nicknames, sentences, and hometowns. O’Donnabhain says these modern prisoners came from the same “blackspots of social disadvantage” as prisoners during the Victorian era.
“You see exactly the same dynamic in the sense that it’s primarily the poor who end up in prison and its people from socially disadvantaged backgrounds,” he says.
O’Donnabhain says tourists are curious to explore the island because of its dark past.
“People are drawn to places that are out of bounds,” he says. “If you tell people they can’t go there, they want to see what’s behind the walls.”
