Satan's Hollow in Blue Ash
Blue Ash is known for many remarkable things, like a large 150-foot observation tower at Summit Park, the second location of Over-the-Rhine’s Senate, and a purported tunnel to the netherworld. The story goes that local Satanic groups would meet at a drainage tunnel in Blue Ash to conduct rituals. In doing so, they opened a portal to hell itself. Whoops! The graffiti-tagged abyss has pentagrams and phrases like “Hell lies ahead” sprayed on the walls. Many have reported screams, trapped spirits and apparitions including a demon referred to as “The Shadow Man.” Wanna check it out for yourself? Alas, Satan’s Hollow is on private property.
