1. Woodlawn Cemetery (Forest Park)

There are more people below ground in the Chicago suburb of Forest Park than there are above due to the plethora of cemeteries. This one in particular is haunted by souls who lost their lives in a circus train accident. The crew was heading to Indiana, and while stopped on the tracks, was hit by an oncoming train. A fire was ignited and 85 performers died, most of which could not be identified and were placed in a mass grave. You'll never guess what roams the grounds at night now.

2. Cairo

This somewhat abandoned town is virtually frozen in time from its height in the 1920s. Tucked into a curve of the Mississippi River, it is cut off from the rest of the state, and fell into crime and ruin. Nowadays, crumbling walls, hollowed-out buildings, and decaying homes are mostly what's left, but there are also a few characters who still linger in the town. Maybe you'll get to meet one when you visit.

A landmark on the National Register of Historic Places, there are not many bridges like this steel one in Illinois. In 1980, a woman's severed body was found underneath, and no one ever caught or was able to figure out her killer. Nowadays, locals report an eerie feeling when crossing the bridge.

9. The Murder Castle (Chicago)

This castle constructed by H. H. Holmes, America's first serial killer, is actually a hotel that was built to lure visitors of the 1893 World's Columbian Exposition. Holmes would befriend and then leave his victims (which mostly consisted of pretty women but also included some men and children) in a cell to rot. He was also a scammer known for signing victims up for life insurance and then cashing in when they died.

10. Eternal Silence at Graceland Cemetery (Chicago)

This statue was commissioned in 1909, and it used to be all the same color, but time (or something) wore the face pitch black.

What's for sure is that this figure is disturbing even without the haunting tales.
