From the Swiss Riviera, the Ghosts of Château de Chillon is said to haunt the place. Deep in the dungeons, jewish prisoners accused of spreading the plague, those accused of witchcraft and the political enemies of The House of Savoy are still lingering.
There are seven pillars of Gothic mould,
In Chillon’s dungeons deep and old,
There are seven columns, massy and grey,
Dim with a dull imprisoned ray,
A sunbeam which hath lost its way,
– The Prisoner of Chillon, Lord Byron
On a rocky islet along the pristine shores of Lake Geneva, the Château de Chillon is one of Switzerland’s most iconic medieval fortresses and one of the most visited historical buildings in Switzerland. Especially as it was this castle Lord Byron visited in the dark summer of 1816 with his friends, and where the birth of Frankenstein and The Vampyre came after him and his literary friends visited. Its postcard-perfect setting near Montreux, framed by mist-clad mountains and shimmering waters in the Swiss Riviera, belies the darker currents of history and folklore that swirl within its ancient walls.

For centuries, Château de Chillon has been a site of power, imprisonment, and bloodshed and was never captured during a siege. Chillon’s doomed inmates entered the castle dungeon through a thick wooden trap door set into the stone castle floor, descended a rough wooden ladder, and found themselves in a small cave with prisoners chained to the pillars. And it is said that not all who entered its gates ever truly left.
A Fortress of Shadows
Though Château de Chillon’s earliest recorded mention dates to 1150, under the House of Savoy, archaeological evidence suggests a fortified structure stood on this small outcrop as early as Roman times as it was a strategic way through the Alps. In 1224, Thomas I of Savoy ordered the castle to be strengthened and decorated as he wished to make it his main residence. The castle’s strategic location along a key trade route made it both a prized stronghold and a place of grim authority. This century was also when they built a prison in the underground, previously used as food storage and weaponry.
In 1342, the Black Death began to claim victims in the area and, wishing to find somebody to blame for the outbreak, Christians accused the Jews who lived there of poisoning water supplies and thus causing the plague. Since 1284, there had lived a group of Jews in the town called Villeneuve and in September in 1348, the Jews were sent to the dungeons for torture. At that time the Château de Chillon was under the rule of Amédée VI of Savoy.
These unfortunate souls were arrested and taken before the Count of Savoy at Château de Chillon. Local Christians who had been friendly with the Jews were also treated in the same way and it is said that the prisoners were burned on the sides of the lake after a forced confession after torture.
The Château’s reputation for cruelty is largely due to its forbidding dungeons — cold, vaulted chambers hewn directly into the bedrock. It is also said that the chancellor of Savoy in 1455 was drowned in the lake after being questioned in Chillon. These prisons, with their damp walls and crude restraints, have witnessed centuries of torment, rebellion, and death. And according to enduring legend, many of those wrongfully punished still linger in spectral form.
The Restless Spirit of François Bonivard
The castle’s most famous ghost is said to be François Bonivard, a Genevan monk, historian, and political dissenter of the 16th century. Back then, the Savoy district was a separate country ruled by the dukes and counts, looking at Geneva as theirs. Bonivard, a libertine and revolutionary, thought otherwise and fought back. Bonivard was imprisoned in Chillon’s dungeons in 1530 for opposing the Bishop of Genova and the Duke of Savoy’s oppressive rule over Geneva. For six years, he was captured at Chillon, where it his treatment gradually worsened. It is said for two years he stayed in a room in the castle before being thrown in the dungeon where he endured brutal captivity, shackled to a stone pillar that still stands in the castle’s underground vault for six years.
While Bonivard was eventually liberated when Bernese forces seized the castle in 1536, legend holds that his spirit, embittered and vengeful, remains. He died in Geneva after a life of extravagant lifestyle and perpetual debt in 1570.
Visitors and staff have long reported unnerving sensations in the dungeons like sudden drops in temperature, fleeting shadows, and the unmistakable clank of unseen chains in the oppressive gloom. Some claim to have glimpsed a robed figure silently pacing between the columns, his face obscured but his presence undeniable.
Lord Byron’s 1816 poem, “The Prisoner of Chillon,” immortalized Bonivard’s ordeal and helped enshrine the castle’s eerie reputation. Byron himself carved his name into one of the dungeon’s pillars — a mark still visible today — and reportedly felt a chill pass over him in the exact spot where Bonivard was held.
The Tragic Story if Erdelinde and the Breaker
One of the most tragic stories in the history of Château de Chillon occurred in 1382. Sir Raoul de Monthenard, a cruel tyrant nicknamed “The Breaker,” then master of the castle, wished to marry the daughter of his first cousin, a beautiful girl called Erdelinde. But she was in love with a young man, named Mainfroi de Luceus, whose father was the sworn enemy of Sir Raoul. Afraid of his anger, Erdelinde and Mainfroi married secretly and later Erdelinde had a baby.
When Erdelinde’s father died, Sir Raoul seized her by force and took her to Chillon, where he arranged for a priest to marry them in the castle chapel. The priest who was to perform the ceremony was the same one who had already married Erdelinde in secret and, as soon as he saw her, he refused to perform the ceremony, enraging Sir Raoul..
Meanwhile, Erdelinde had arranged for her baby to be brought to the chapel to prove to Sir Raoul that marriage to him was impossible. When he saw the child, the master of Chillon, in a terrible fury, seized the baby and hurled it through the chapel window into the lake below. Erdelinde immediately leaped after it, and both mother and child drowned.
Grief-stricken, the true husband of Erdelinde, Mainfroi de Luceus, challenged Sir Raoul to a duel in which he received severe wounds from which he died.
People have later claimed to have seen her ghost walking along the lake, looking for her baby as her anguished screams pierce the night. Sir Raoul de Monthenard is also said to haunt the hallways of his castle, roaming around with a maniacal look and evil smile on his face.
Other Hauntings and Dark Whispers at Château de Chillon
He died—and they unlocked his chain,
And scooped for him a shallow grave
– The Prisoner of Chillon, Lord Byron
While Bonivard’s ghost commands the most attention at Château de Chillon, other strange occurrences haunt the castle grounds. In the upper halls, guests have described hearing footsteps in empty corridors, doors that creak open of their own volition, and unexplained cold spots in rooms warmed by roaring fires. Visitors have come back with stories about being pushed against the wall by an unseen force.
There was another terrible time at Chillon when, between June 9 and September 26, 1613, twenty-seven people accused of witchcraft were executed there. In 1613, the Bernese convicted 27 people as witches and burned them in Chillon’s courtyards. The spirits of these as well is said to linger within the halls.
Another ghost said to haunt Château de Chillon is simply called The Man in Rags. This story comes from a tour guide who claims this raggedly clothed man came through the walls, saliva dripping from his open mouth, blood dripping from his body. One of the former prisoners of the castle. The tour guide claims this specter was also seen by a maintenance worker who quit the same day.
A Place of Uneasy Beauty
Today, the Château de Chillon is one of Switzerland’s most visited historic landmarks, drawing travelers eager to marvel at its medieval architecture and panoramic lake views. But beneath the idyllic surface lingers the weight of history — and the restless spirits born from centuries of confinement and cruelty.
As dusk falls over Lake Geneva, and mist creeps once again around the castle’s stone foundations, those who linger may find themselves catching an icy draft where none should exist, or hearing the mournful clink of ancient chains in the deep, shadowed vaults below.
The Château de Chillon stands not just as a monument to medieval splendor, but as a sentinel of the lingering dead — a place where history and legend bleed inseparably together.
