Travel is one of the most popular pastimes during holiday seasons but why not spice up your next trip by having a theme: a spooky travel theme. This list looks at ten of the scariest places on the face of the earth (many of which are unlikely to be known to the average person). Be sure to name any others you think worthy of inclusion in the comments.

#10. Hill of Crosses, Lithuania

1The Hill of Crosses, Kryzi? Kalnas, located 12 kilometers north of the small industrial city of Siauliai (pronounced shoo-lay) is the Lithuanian national pilgrimage center. Standing upon a small hill are many hundreds of thousands of crosses that represent Christian devotion and a memorial to Lithuanian national identity. The origin of the first crosses is unknown, but despite repeated attempts by the occupying communists in the 20th century to destroy the hill and remove the crosses, they still come back in their thousands. You can view a panoramic image of the hill here. While the subject is not scary in itself, the concept of a hill with mysterious crosses appearing is a little disturbing.

#9. St. Louis Cemetery, New Orleans

2It would be wrong to write a list like this without the inclusion of at least one cemetery. Saint Louis Cemetery is the name of three Roman Catholic cemeteries in New Orleans, Louisiana. All of these graves are above ground vaults; most were constructed in the 18th century and 19th century. The above-ground tombs, which some say are required here because the ground water levels make burial impractical in New Orleans, are strongly reminiscent of the tombs of Père Lachaise cemetery in Paris. St. Louis Cemetery #1 is the oldest and most famous. It has been in continuous use since its foundation. Due to crime risks, it is inadvisable for individual tourists to visit the cemetery on their own, but it can be safely visited with tour groups. The renown Voodoo priestess Marie Laveau is believed to be interred in the Glapion family crypt. Other notable New Orleanians here include Bernard de Marigny – the French-Creole playboy who brought the game of craps to the United States, Barthelemy Lafon – the architect and surveyor who allegedly became one of Jean Lafitte’s pirates, and Paul Morphy, one of the earliest world champions of chess. Delphine LaLaurie, the murderous socialite is also rumored to lay in rest here.

#8. Mary King’s Close, Scotland

3For years the hidden underground closes of Mary King’s Close, in the Old Town area of Edinburgh, Scotland, have been shrouded in myths and mysteries. Tales of ghosts and murders, and myths of plague victims being walled up and left to die abounded. in 1645 life of the close was shattered forever. The plague struck this little community and there is a tale that the local council decided to contain the plague by incarcerating the victims, bricking up the close for several years and leaving them to die inside to die. It is likely that this is why the close was nicknamed ‘street of sorrows’. It certainly has a reputation of being haunted, one ghost of a little girl ‘Annie’ has become something of a local celebrity. Sad because she had lost her favorite doll, there is now a room full of gifts left by visitors for her. Pictured above is the plague suit of Dr George Rae who worked in the area.
