  • The White House - its kitchens are reputedly haunted by Mamie Eisenhower, wife of President Dwight D. Eisenhower. Mrs. Eisenhower had a difficult relationship with household staff who worked in the kitchens. After her husband left the presidency, kitchen staff during the Kennedy and Johnson presidencies reported finding the kitchen reorganised overnight back to the way Mamie had demanded. After the death 'Mamie reorganisations' were reported by a number of staff in the kitchen who could find no explanation for the changes and none of the security staff on duty saw anyone entering or existing the kitchens at night. Some staff claimed to have seen Mamie on occasion in the kitchen rummaging through cubbords.

  • Alcatraz - a notious now closed American jail where claims have been made by visitors and tour guides working there of screams, slamming jail doors and footsteps.

  • Ohio State Reformatory - nineteenth century prison reputedly haunted by a Mrs Glattle, who was killed in 1950 when a gun accidentially fell, went off and killed her.

  • The Old Bailey, London's main criminal court. A person of unclear gender supposedly appears in the building during major trials. These appearances have been allegedly witnessed by judges, barristers and policemen.

  • Mount Everest - the ghost of a climber has allegedly been seen by other climbers, two of whom in 1975 claimed to have shared a snow hole with the ghost during their climb.

  • Cranborne Chase in Dorset in the United Kingdom. A ghost riding a horse bareback and wielding an axe, is supposedly seen. Witnesses described him as looking like stone age warrior.

  • Windsor Castle - home of English and British royalty for 1000 years. Numerous ghosts are supposed to have been seen, including Anne Boleyn, who supposedly runs down a corridor screaming. Among those who claimed to have seen the ghost, who sometimes is said to be carrying her head, are King George VI, William Ewart Gladstone and Andrew, Duke of York.

  • Dublin Castle - in the mid-nineteenth century a member of the Lord Lieutenant of Ireland's staff reported seeing two file clerks walk through his office carrying papers and chatting before exiting through a long sealed up door. The same two 'visitors' have supposedly been witnessed by people working in the Castle. On one occasion they were heard talking about Theobald Wolfe Tone, an Irish rebel executed after a failed rebellion in 1798.

  • Versailles Palace, outside Paris. In 1889 two school teachers on a visit to the Palace grounds walked through a set of Palace gardens, saw a physically deformed man on a swing in eighteenth century clothes, and entered the Chapel Royal where a Mass was being sung on the High Altar. When they returned the next day they found the gardens completely changed and the door they supposedly entered the Chapel Royal through locked with a rusted lock. Staff at the Palace insisted that the grounds they claimed to have walked through didn't exist and the door in question had not been opened since 1789. Both women were sacked from their teaching posts and called liars. Years later, a file was discovered which showed that the grounds at Versailles had once looked as the women described and the man they described seeing matched the description of Queen Marie Antoinette's brother. But the part of the grounds the women had walked through had been remodelled during Napoleon I's reign and details of the grounds up to that point forgotten except in long unread state files. How the two women could have seen the gardens as they had existed in 1789 (one hundred years prior to their visit) when no-one in their lifetime knew what the grounds had been like, and when the only file describing the layout was locked up unread in the French national archive, remains a mystery.
