Some of the eeriest abandoned places in Illinois are also among the most beautiful. After all, there's a strange fascination surrounding once-bustling buildings and formerly thriving communities that now sit in ruin. While a sense of sadness permeates these spots, we can't help but be fascinated by the way they've been reclaimed by nature and, sometimes, found themselves at the center of local legends. While we don't condone trespassing, many of the most iconic abandoned places in Illinois can be admired via urban explorers' photography.

Get out and explore the deserted pockets of our beautiful state with this handy list. Check it out:

1. Ashmore Estates - Ashmore

Built in 1919, this long-abandoned building has a fascinating history. Following years of use as an almshouse, it operated as an asylum from 1959 to 1986. Today, it is rumored to be haunted by the ghosts of residents who once called it home. While renovation efforts have taken place over the years (with some still reportedly in the works), there's a real sense of spookiness about Ashmore Estates.

2. Old Shawneetown - Gallatin County

Due to flooding of the Ohio River in 1937, this once-thriving town is currently home to fewer than 300 people. Most businesses are shut down and most buildings are abandoned places locals no longer frequent. While Old Shawneetown has a haunting past, there has been blooming from the rubble with the establishment of modern-day Shawneetown, which rebuilt in the generations following the flood, not too far from these abandoned neighborhoods in Illinois.

3. Cahokia Mounds - Collinsville

Though once a large Indigenous community that thrived, this plot of land has been left to decay since about the 1400s. Visitors can still see remnants of the community and learn how they engineered their way of life. Talk about a fascinating way to connect with the earliest people who called our region home.

4. Cairo - Alexander County

Located at the confluence of the Mississippi and Ohio rivers in Southern Illinois sits an abandoned town you must visit before it withers away completely. It is currently home to fewer than 3,000 people and is rumored to be haunted. With a tragic and complex history, there's a lot to learn about Cairo, whether you believe in these ghost stories or not.

5. Bachelor's Grove Cemetery - Midlothian

Burials at this cemetery began around 1840 and ceased around 1989. It is small with only 82 plots and is believed to be very haunted, with reports of everything from strange creatures to floating orbs among the tombs. Just 25 miles from Chicago, the cemetery is one of Illinois' most famous haunted places.Learn more about this chilling place in this YouTube video from grimmlifecollective:

6. Iron Furnace - Hardin County

Situated in the Shawnee Forest along the Ohio River near the town of Rosiclaire is a historic, abandoned furnace that once used to smelt iron that was mined nearby. It was in operation from 1839 to 1883, though it went into decline long before that. While it might be a little-known wonder here in Illinois, we think it's well worth seeking out when you're looking for an out-of-the-box roadside stop.

7. Damen Silos - Chicago

Located at 29th and Damen on the banks of the Chicago River, this is a popular spot for teens to roam. It is technically illegal to go here, so we don't advise stopping by to see for yourself. Built in 1906, these 15-story grain silos were abandoned after an explosion in 1977, yet enough of its secret tunnels and rail line are still standing. These fascinating silos conjure memories of a long-gone era in Chicago and its surrounding areas.

8. Savanna Army Depot - Carroll and Jo Daviess counties

Located along the Mississippi River, this building was once used by the U.S. military to store equipment for the Rock Island Arsenal, which is nearby. The depot was in use between 1917 and 2000. In its heyday, it spanned 13,000 acres, though most of that is now a nature preserve.

9. Joliet Correctional Center - Joliet

Though mostly deteriorated, there are 24 buildings on this campus that had been in operation as a jail from 1958 to 2002. It is surrounded by high walls with barbed wire and includes guard towers, a hospital, a gym, a cafeteria, a church, and more. There's something fascinating yet sad about imagining the experiences of prisoners here during the institution's operational years.

10. Manteno State Hospital - Kankakee County

Horror movies about old psych wards are probably all based on this one. Known for being the site of lobotomies, shock treatments, and other unpleasant procedures, it was in operation from 1930 to 1989, though it was at peak capacity in the 1950s. While the vast majority of the grounds have been demolished or destroyed, a small number of buildings remain standing and provide plenty of content for ghost stories throughout Illinois and beyond.
