These Super-Scary Stories Will Keep You up at Night

Five years after the Civil War, Birmingham, Alabama, was founded. With its birth in 1871 came the need for tons of pig iron to fix the U.S.'s crumbling infrastructure, so Colonel James Withers Sloss began to build Sloss Furnaces. A year later, the company opened its doors to hundreds of employees, according to its official website. Jobs on blast furnaces were advanced but also dangerous, and many workers started falling to their deaths in the furnaces.

By the early 1900s conditions had worsened with a cruel foreman, James "Slag" Wormwood, who took dangerous risks to increase production, according to Reader's Digest. During his tenure at Sloss, nearly 50 employees died on-site, and many others were involved in terrible accidents. Allegedly, his workers threw him into the furnace in retaliation in 1906.

Today you can still walk the grounds of Sloss Furnaces, if you dare. You may even hear Slag's voice yelling, "Get back to work!" and witness other paranormal experiences.
