Chicago’s West 63rd Street Post Office was built in 1938 over the site of what its creator referred to as “The Castle”, and in 1902 an Ohio Daily News article called it Chicago’s Ghost Castle. Whatever you want to call it, this site was once or possibly still is the home to a notorious killer.

A figure who built a home that included a 2nd floor full of secret passages, trap doors, and hidden staircases. The basement so notorious that a crowd would lay on the sidewalk and try to peer through the cracks as it was excavated.
