It was the location of the St. Valentine's Day Massacre and was destroyed by fire in 1871. Both of these incidents have something in common: they make Chicago a prime location for paranormal activity.

Like many well populated city, Chicago has its share of ghost stories. Here are just a few to give you a taste of haunted Chicago.

Sounds somewhat bland: Clark Street Warehouse. However, it was the site of Chicago's Valentine's Day Massacre and while the warehouse itself went through many incarnations after the massacre, it was a Canadian entrepreneur by the name of George Patey who saw dollar signs when he came across the bullet marked bricks of one of the demolished walls.

Patey confiscated the bricks and began selling them as "souvenirs" of the massacre. However, it wasn't long before his customers began wanting a refund. Or, at the very least, wanting George to take them back.

Those who bought the bricks claimed to have experienced a sudden bout of bad luck claiming that the bricks had brought them everything from financial ruin to death.

Whether or not the bricks were haunted, to this day, people who pass by the site of the Valentine's Day Massacre claim to hear the sounds of that fateful day ringing in their ears as the ghosts of the victims and those who witnessed the crime relive the moment over and over and over again.

Chicago's John Hancock Center has a bloody history. It has been the site of numerous suicides and murders - many of which have involved the victims plummeting to their death.

• Lorraine Kowalski, only 29 at the time, fell from her boyfriend's apartment which sat on the 90th floor. This was made even more perplexing by the fact that Kowalski broke through the apartment's glass window pane.
• It would be only four years later when another death occurred, much in the same way, when a man working as a radio technician on the 97th floor.
• In 1978, a man was shot and killed on the 65th floor.
• Perhaps one of the most memorable deaths in recent years, SNL and film comedian Chris Farley
• However, one of the most perplexing incidents occurred in 2002 when three women were killed as a result of aluminum scaffolding from the 43rd floor of the building falling and killing three women who weren't even in the building at the time.

So why has the building had so much bad luck? According to legend, the building was built on "cursed land." Cursed when the man who owned the land, Cap Streeter, swore on his deathbed that no one would be happy on his land again following a lengthy battle with the city over the tract of land.

Whether it's a curse or just really, really bad luck, no one knows, but paranormal experts are convinced: The John Hancock Building is bad news. Apparently filmmakers bought into the legend to some degree, the John Hancock Center was the location of the film, Poltergeist III.

Chicago's most famous ghost, Resurrection Mary, is one of Chicago's infamous "hitchhiking ghosts."

Sightings of Resurrection Mary date back to the 1930s. Drivers making their way along a lonely Archer Avenue might come upon a young woman wearing a white dress. Many of those who saw her claimed that she attempted to throw herself into the path of oncoming vehicles. These occurrences always seemed to happen as motorists were passing by the Resurrection Cemetary.

Resurrection Mary seemed to prefer young men who were alone and some even claimed to have met her while scoping out the local ballrooms of the time. There, she would give the young men directions to her house along Archer Avenue.

Those who have researched the ghost known as Resurrection Mary seem to agree that the real identity of the woman is one of a young woman who was killed by a hit and run driver as she was walking home from a local ballroom.

Those who have given Mary a ride say that she usually disappears just as the driver passes the Resurrection Cemetary, where the young woman was buried.

The ghost of Resurrection Mary continues to be seen, though less seldom than in the past. Versions of the tale have made their way into films, television series and movies with perhaps one of the most notable being the television series, Supernatural.
