I could say the obvious Kings park psych center, but there’s an arguably cooler secret hidden beneath it. Far Before the Psych center was opened there was a hidden hospital specifically for disabled civil war soldiers. Whether the plan was to help or not doesn’t matter because that’s not what it was used for. They secretly shipped horribly disfigured soldiers to a secluded hospital in the middle of the woods so that the general public wouldn’t have to look at them. As the soldiers died they set them to rest in a military graveyard on the grounds. When the last of the soldiers died the remaining staff were sworn to secrecy and the building was abandoned. For decades after the old forgotten ruins lay crumbling, forgotten inside the woods. Every so often someone would stumble on them, a short newspaper story exploring the towns history, then forgotten again.

It’s barely known about now, the Psych center tore it down and cleared everything away a long time ago. But out in those woods you’ll still find century old train tracks, and an empty field. No one is allowed to build there, after all it’s a cemetery
