The biggest spiral staircase I’ve ever seen. Six complete revolutions! No way was I going to climb it, though. This place is in advanced decay, and a staircase collapse could easily be fatal, even if it happened while I was only a few steps up. After I got home I found an urbex website with photos from the top someone had taken five or six years ago. That photographer didn’t get into specifics, but I think his balls must be substantially larger and/or more numerous than mine. More photos from this power house in Utica, N.Y., are HERE.
