When you think you have seen everything above ground in Mississippi, head below ground to one of the only mines in Mississippi, which is officially known as Chalk Mine Hollow! Among the most intriguing abandoned places in Mississippi, the secluded and deserted mine has been out of commission for decades. However, that has not stopped people from exploring its intertwining passageways. Like something from another world, the underground site boasts some incredible Mississippi history, making it more than worthy of an adventure.

Quite possibly one of the state’s best kept secrets and one of the most unique abandoned places in Mississippi, Chalk Mine Hollow is hidden underground in the small town of Iuka.

Accessible by boat or by foot, it’s just off the Tennessee River, not far from Pickwick Lake.

One of the only mines in Mississippi, it is situated at the end of a short, well-beaten path through the woods.

Spray-painted trees let you know you’re headed in the right direction.

It's a unique sight, and almost impossible to miss.

The mine’s entrance is carved into the side of the hill.

However, it’s hard to miss, since, like the trees, it been spray painted.

From the outside, the mine doesn’t appear to be very big, but it is actually huge on the inside.

Featuring three long tunnels and a number of connected passageways, it is the size of a Wal-Mart. The site was originally used during the Civil War to mine for chalk – hence the name Chalk Mine Hollow. The chalk was then used to make gunpowder.

There is not much info on the mine. Even records on its closing date are obscure, but it appears to have closed sometime around 1890.

Lots of local legends claim that the mine was used as a makeshift hospital during the Civil War; however, there’s no proof. Although, records indicate that it is likely it was used as a temporary shelter at some point during the war. One thing is for sure, though. The abandoned mine in Mississippi has continued to intrigue adventure-seekers of all ages. The mine is open to all, who wish to explore its maze of passages. Remember, though, it is unattended, so you will be exploring at your own risk. Also, you are responsible for bringing your own supplies (i.e. flashlight, water, etc.).
