From European castles to abandoned prisons, the ghostly spirits and disembodied voices of these haunted places will chill you to the bone.

Paranormal activity, demonic presences, bone-chilling screams, and so much more are said to permeate the grounds of these 11 haunted places around the world.

Some of these sites have long histories of hauntings and others have shorter ones, but the varied stories behind these ghost-filled halls remain bone-chilling either way. After learning the full tales of these supposedly haunted places, even the biggest non-believers may think twice before daring to enter one of them.

The Most Haunted Places In The World: Raynham Hall – Norfolk, England

Nestled in the countryside of Norfolk, England, Raynham Hall was built by wealthy politician Sir Roger Townshend and has been in the Townshend family for 300 years.

Much more infamously, the hall is the setting for one of the most famous supposed ghost photos ever taken. In 1936, the photo of a woman called the “Brown Lady” was captured by Country Life magazine, depicting a white figure descending a set of stairs.

The apparition is named for the color of the ghostly woman’s dress, which she is said to always be wearing — but no one is exactly sure of the identity of the Brown Lady.

Stories of a ghost haunting Raynham Hall started in 1835 — when guests present at a Christmas party in the house described and sketched an apparition dressed in brown — and ran rampant throughout the late 1800s and early 1900s as the hall gained a reputation as one of the most haunted places in England.

Some legends say that she is the ghost of Lady Dorothy Walpole, the sister of Robert Wapole who was the first Prime Minister of Great Britain. Lady Dorothy was married to Charles Townshend who was a cruel man with a hot temper.

He accused his wife of adultery and promptly locked her away inside the home. He forbid her from having any contact with the outside world and even barred her from seeing their children.

A funeral was thrown for poor Lady Dorothy in 1725, but many believe it was false and that she actually lived for many years as a prisoner of her own husband. And, if the legends are to be believed, she still roams the halls of Raynham to this day.

The Myrtles Plantation – St. Francisville, Louisiana

Built in 1796 by General David Bradford, the Myrtles Plantation is home to centuries of history — and, allegedly, its fair share of ghosts that makes it one of the most haunted places in the world.

Upon his death, Bradford gifted the plantation to his daughter and her husband, Clarke Woodruff. The couple did not have a happy life while they lived inside the home and were faced with many tragedies. Of the three children that the couple had, only one made it to adulthood.

The most famous ghost reportedly roaming the plantation is Chloe, a slave who became Woodruff’s mistress. Chloe was terrified that Woodruff’s wife would find out about their affair so she eavesdropped on the family’s conversations. However, she was caught snooping and had her ear cut off for her crime.

Hungry for revenge, Chloe poisoned the food of Woodruff’s wife and two of their children while he was away, and after a few days, they were dead. The other slaves were afraid of what Woodruff would do upon returning and hung Chloe themselves for her deadly actions.

They removed her dead body from the tree from which they hung her and then threw it into the river, but legends say that her spirit lived on and still haunts the house.

Another family, the Meyers, purchased the home in the 1970s and opened it as a bed and breakfast. Almost right away, strange things were said to have started happening.

Guests claimed to hear strange noises, and some even said they saw the spirit of Chloe. In 1992, the owner claimed to have captured Chloe’s spirit in a photograph:

This isn’t the only time the guests claimed to have seen the ghost of one of the home’s former residents. Some people claimed to have seen young girls in antebellum clothing in the windows and others say they’ve seen the ghosts of Woodruff’s children in the mirror near the room where they were supposedly poisoned.

All in all, 10 murders are allegedly supposed to have happened on the plantation’s property, but many, if not all, are chalked up to legend. If you would like to figure out for yourself whether this is one of America’s most haunted places, the plantation is still open as a bed and breakfast.
