Rising quietly from the waters of the Trondheim Fjord, Munkholmen appears peaceful by day. Tour boats glide past its rounded shores, seabirds cry overhead, and the island seems little more than a picturesque landmark. But beneath this calm surface lies one of Norway’s darkest historical sites, a place shaped by execution, imprisonment, and spiritual isolation.

For centuries, Munkholmen has carried a reputation as a haunted island where the past has never fully loosened its grip.

From Holy Ground to Place of Execution

Munkholmen’s troubled history began long before its stone walls were raised. In the early Middle Ages, the island served as a site of executions. Criminals and enemies of the crown were brought across the water and put to death, their bodies often left exposed as a warning to others on spikes. It is said that Olav Tryggvason had the heads of Earl Håkon and the slave Kark impaled here in the year 995.

Later, a Benedictine monastery Nidarholm Mariakloster was established on the island, giving Munkholmen its name as the country’s oldest monastery. The monks came seeking solitude and devotion, but even prayer could not erase the island’s grim legacy. Fires repeatedly destroyed the monastery, and many believed the land itself was cursed, soaked in blood long before the first chapel stone was laid.

The Prison Island

Munkholmen’s darkest chapter began in the 17th century, when it was transformed into a state prison and fortress. Political prisoners and criminals. Some were kept in damp underground cells where daylight never reached. Others were chained in small stone chambers, listening to the waves crash endlessly against the walls.

One of the most infamous prisoners was Count Peder Schumacher Griffenfeld, once the most powerful man in Denmark-Norway. Under Christian V he became the king’s foremost advisor and by far the de facto ruler of Denmark-Norway.

Peder Griffenfeld:Peder Griffenfeld (1635–1699) (original name Peder Schumacher ) was a Danish count and statesman, who was Chancellor of the Crown from 1673. He spent 18 years on the island in solitude and is believed to be haunting it. 

Griffenfeld failed in his efforts to prevent war, and in 1675 Denmark-Norway entered into armed conflict with Sweden, the Scanian War . Various negotiations surrounding the beginning of the war and his friendliness to the French contributed to his being accused of treason and lèse-majesté .

After falling from royal favor, he was imprisoned on Munkholmen for nearly two decades. He spent his time reading, teaching children and writing small religious writings. After this, he was moved to Trondheim city, where he lived under guard for the last time, and died the following year.

Victor Hugo published the novel The Prisoner on Munkholmen in 1831 about Griffenfeld’s time in prison. Visitors and guards later claimed that his spirit never left, pacing unseen corridors long after his death.

Many prisoners died on the island from disease, exposure, or despair. Their bodies were buried nearby or cast into the sea. Over time, stories spread of anguished voices heard at night, echoing from empty cells and sealed passageways.

Ghostly Sightings and Unexplained Phenomena

Reports of hauntings on Munkholmen date back hundreds of years. Guards once spoke of shadowy figures moving along the fortress walls after sunset, disappearing when approached. Others described the sound of chains dragging across stone, even though no prisoners remained.

Some report sudden drops in temperature inside the fortress, accompanied by an overwhelming feeling of dread. Doors have been heard slamming shut on calm days, and footsteps echo where no one stands.

The story was popularized once again when the papers started to publish a picture, claiming to show the ghost roaming the island in 2008.

Tommy Skog and his son were visiting the island and was taking pictures of the prison towers where an oval hole in the wall on the first floor caught his attention. When looking at the picture, he was certain he had taken a picture of the ghost of a man, sitting in the opening. 

An Island That Never Truly Sleeps

Today, Munkholmen is a popular destination in summer, but its darker reputation persists. Locals often say the island feels different once the last boat departs and silence returns. As dusk settles, the fortress seems to watch the fjord, its thick walls holding centuries of suffering within.

Whether haunted by monks, prisoners, or those executed long before history was written down, Munkholmen remains a place where the past feels uncomfortably close. The sea may surround it, but it has never truly washed the island clean.
