LONDON
Watch closely as London hosts the 2012 Olympic Summer Games. After 20 centuries of human habitation, it is reputed to be the most haunted city in the world. Jack the Ripper committed his murders in the seedy Whitechapel area in 1888. His crimes remain unsolved, yet his five female victims are still said to wander the East End streets in spiritual form. Other East End specters: Roman soldiers, a sea captain and a ghostly, horse-drawn black carriage.

The grim Tower of London is haunted by all manner of famous victims, such as Anne Boleyn and Lady Jane Grey, whose nine-day reign as queen ended in beheading at the command of Mary Queen of Scots. St. Bartholomew church is noted as the most haunted church in London, hosting the spirit of its monk founder, Rahere, and the tortured souls of those executed nearby under Henry VIII's brutal rule. Visitors claim to hear their voices and smell the scorching flesh of one monk burned alive. London's theaters are notoriously haunted, such as the Theatre Royal, whose "Man in Grey" appears during daylight hours. Even the transportation systems are said to host spirits — ghosts roam multiple "tube" subway stations, and radars at Heathrow Airport have detected what some say is the spirit of a man killed in a crash in 1948.

This charming city brims with Southern hospitality — for countless ghosts. >>
