Laundry Kit Looking into the tunnel system from below the Women’s Ward. The tunnels were used mostly by staff to move food and laundry. Similar Images ...based on the tags: basements, carts, peeling-paint, pipes, tunnels, windows... Next to the generator room is the pump room, which moved steam around the complex. In the distance, the San Haven Sanatorium water tower. Imagine with yellow window guards are eyebrows and the open windows are the eyes. This headframe seems a bit curious. A machine to cast copper billets. Pipes to channel nitrose (think nitro glycerine) infused acid through the building. Under the monster and its teeth. Scrappers infamously gutted the factory, but this one green conduit going from the sintering floor all the way to ground level seems to have been spared. I didn’t test the rungs, but I bet the view was incredible. A view of the hallway outside of the auditorium.
