Castles have always captured our imagination with their towering walls and mysterious chambers, but some hold secrets far darker than medieval politics or forgotten treasures. These ancient fortresses have witnessed centuries of human drama—from brutal executions and tragic deaths to unexplained phenomena that continue to puzzle visitors today.
The stories within these stone walls aren’t just tales from dusty history books. Here is a list of 20 castles where the past refuses to stay buried, and the boundaries between history and mystery blur in the most unsettling ways.
Tower of London, England
The Tower of London stands as perhaps the most notorious fortress in the world, with nearly a thousand years of bloodshed etched into its very foundations. Anne Boleyn, executed here in 1536, reportedly roams the grounds carrying her head under her arm, while the ghosts of two young princes—murdered in the Bloody Tower—still play in the corridors where they met their grim fate.
The Tower’s Yeoman Warders have documented countless supernatural encounters, from phantom footsteps echoing through empty halls to the unexplained appearance of medieval figures in full regalia.
Edinburgh Castle, Scotland
Perched dramatically on an extinct volcano, Edinburgh Castle has endured more sieges than almost any other fortress in Europe, leaving behind a tapestry of tormented spirits. The headless drummer boy, first spotted in 1650, continues to beat his ghostly rhythm before times of danger or attack.
Visitors frequently report sudden temperature drops in the dungeons, where French prisoners from the Seven Years’ War carved their names into the walls before dying in misery.

Bran Castle, Romania
While Bram Stoker never actually visited this Transylvanian fortress, Bran Castle’s connection to Vlad the Impaler gives it a genuinely terrifying history that rivals any vampire tale. The real Vlad Dracula used the castle as a strategic stronghold, and his brutal methods of dealing with enemies—impaling them on wooden stakes—created a legacy of fear that persists today.
Modern visitors describe an overwhelming sense of dread in certain rooms, particularly in the narrow stairwells where Vlad once planned his most vicious campaigns.
Château de Brissac, France
The ‘Green Lady’ of Brissac has been terrifying guests for over two centuries, appearing as an elegant woman in a green gown with black voids where her eyes should be. Nobody knows her true identity, though theories range from a medieval lady-in-waiting to a murdered duchess. Still, her presence is so well-documented that the current Duke of Brissac treats her as just another family member.
She’s been spotted in mirrors, standing at the foot of beds, and gliding through the castle’s opulent halls as if she still owns the place.
Leap Castle, Ireland
Built on a site where ancient Celtic druids once practiced their darkest rituals, Leap Castle earned its reputation as one of Ireland’s most haunted locations through centuries of clan warfare and betrayal. The O’Carroll family, who owned the castle for 400 years, were particularly brutal—one brother even killed a priest during mass in the castle’s chapel, which is still called the ‘Bloody Chapel’ today.
The castle’s ‘oubliette’—a trap door leading to a pit filled with spikes—was discovered in the 1900s along with three cartloads of human bones.

Warwick Castle, England
This perfectly preserved medieval fortress has accumulated over 1,000 years of ghostly residents, from Sir Fulke Greville, who was murdered by his servant in 1628, to the mysterious grey lady who roams the castle’s towers. The castle’s torture chamber once housed some of England’s most creative methods of extracting confessions, and visitors often report feeling watched or touched by invisible hands in these lower chambers.
The ghost of a young boy in Victorian dress appears so frequently that staff members have nicknamed him and simply acknowledge his presence during their daily routines.
Poveglia Island Castle, Italy
This small island fortress near Venice holds one of history’s darkest secrets—it served as a quarantine station for plague victims and later as a mental hospital where a sadistic doctor conducted horrific experiments. Over 160,000 people died on this tiny island, and their ashes literally make up 50% of the soil.
The few brave visitors who’ve managed to reach the abandoned castle report an immediate sense of overwhelming despair and the sound of screaming carried on the wind.
Château de Versailles, France
Beyond its glittering halls and famous mirrors, Versailles harbors the spirits of those who died during the French Revolution’s most violent days. Marie Antoinette’s ghost has been spotted in her private chambers, while phantom courtiers in elaborate 18th-century dress continue their eternal dance in the ballrooms.
The castle’s servants’ quarters tell an even darker story, where overworked staff died from exhaustion and disease, their spirits now trapped in the endless routine of serving masters who no longer exist.

Predjama Castle, Slovenia
Built dramatically into a cliff face, this castle served as the hideout for the rebellious knight Erazem Lueger, who was killed in the most undignified way possible—struck by a cannonball while using the privy in 1484. His ghost reportedly still roams the secret passages he once used to smuggle supplies during a year-long siege.
The castle’s location in a cave system adds to its eerie atmosphere, with strange winds and unexplained sounds echoing through chambers carved directly from living rock.
Bodiam Castle, England
This fairy-tale castle, surrounded by a moor, conceals a darker history of border raids and violent conflicts between England and France. The ghost of a young boy, believed to be the son of a castle defender who died during a siege, appears on the battlements at dusk.
Local fishermen on the surrounding moor report seeing the reflection of medieval soldiers in the water, even when no one is visible on the castle walls above.
Kilkenny Castle, Ireland
The Butler family ruled from this stronghold for over 500 years, and their ghosts apparently haven’t gotten the memo that their time is up. The most famous spirit is a lady in white who appears in the castle’s long gallery, believed to be a Butler daughter who died tragically young from a mysterious illness.
The castle’s servants have reported dishes moving on their own in the kitchen and the sound of medieval music playing from empty rooms.

Hohenzollern Castle, Germany
Perched on a mountain peak like something from a Brothers Grimm tale, this castle has been home to Prussian royalty and their restless spirits for nearly 1,000 years. The White Lady, a mysterious figure in flowing robes, appears before the death of any family member, serving as a supernatural harbinger of doom for the Hohenzollern dynasty.
The castle’s chapel is particularly active, with visitors reporting the sound of phantom organ music and the glimpse of medieval figures kneeling in prayer.
Bannerman Castle, New York
This crumbling fortress on a small island in the Hudson River was built by a Scottish immigrant who made his fortune selling military surplus after the Civil War. The castle began deteriorating almost immediately after construction, and a massive explosion in 1920 left it in ruins that seemed to intensify the supernatural activity.
Kayakers and boaters report seeing lights moving through the empty windows and hearing the sound of machinery from the abandoned munitions storage areas.
Castell Coch, Wales
This 19th-century reconstruction of a medieval castle sits atop the ruins of a much older fortress, and the layers of history have created a perfect storm of paranormal activity. The Red Knight, a medieval warrior who supposedly defended the original castle against Norman invaders, still patrols the battlements in full armor.
The castle’s Victorian-era rooms add another layer of haunting, with phantom servants going about their duties as if the castle were still occupied by the wealthy family who built it.

Dunluce Castle, Northern Ireland
Dramatically perched on coastal cliffs, this ruined castle lost an entire wing to a storm in 1639, taking several servants to their deaths on the rocks below. The ghost of Maeve Roe, a young woman who died trying to elope with her forbidden lover, appears on the cliffs during storms, still searching for her lost romance.
The kitchen staff who plummeted to their deaths continue their duties, with visitors reporting the smell of cooking food and the clatter of dishes from the empty ruins.
Glamis Castle, Scotland
Known as the childhood home of Queen Elizabeth the Queen Mother, Glamis Castle harbors secrets that the royal family has never publicly acknowledged. The Grey Lady haunts the chapel, while the mysterious Monster of Glamis—allegedly a hideously deformed family member kept hidden for decades—supposedly still lurks in a secret room.
The castle’s guests frequently report being awakened by someone sitting on their bed, only to find the room empty.
Chillingham Castle, England
This fortress claims to be England’s most haunted castle, and given its history of medieval warfare and a particularly creative torture chamber, that’s saying something. The Blue Boy appears in the Pink Room, glowing with an eerie light before disappearing into the walls, while Lady Mary Berkeley roams the halls searching for her husband, who died in the dungeon below.
The castle even employed a professional torturer whose ghost, John Sage, still enjoys his work in the depths of the castle.

Berry Pomeroy Castle, England
The ruins of this Devon castle are home to two distinct spirits who represent the extremes of medieval women’s experiences. The White Lady, believed to be Lady Margaret Pomeroy, was allegedly starved to death by her jealous sister and now appears to warn visitors of danger.
The Blue Lady, possibly Eleanor de Pomeroy, searches eternally for her lost child, and her appearance often coincides with the sound of a baby crying from the empty towers.
Malbork Castle, Poland
The largest castle complex in the world by land area, Malbork served as the headquarters of the Teutonic Knights, a military order known for their ruthless campaigns against pagan tribes. The grand master’s palace is particularly active, with reports of armored figures walking the halls and the sound of medieval chants echoing from the chapel at midnight.
The castle’s massive walls seem to trap the echoes of centuries-old battles, with visitors frequently reporting the clash of swords and the sounds of battle cries.
Eltz Castle, Germany
Unlike many castles that changed hands through conquest, Eltz Castle has remained in the same family for over 850 years, creating an unbroken chain of family spirits who apparently never left home. The Countess Agnes appears in her medieval gown in the family’s private chambers, while phantom children play in the courtyard as if time has stood still.
The castle’s remarkable preservation has also preserved its supernatural residents, with each room retaining the personality of its long-dead occupants.

Where History Becomes Legend
These castles prove that some stories are too powerful to be contained by death, and their stone walls have become vessels for preserving the most intense human experiences across centuries.
