Exploring the Hidden Tunnels of the Holly Manufacturing Works

We are exploring around Lockport, NY and taking a tour in the hidden remains of the Holly Manufacturing Works.  There were huge underground tunnels that channeled the water in from the Erie Canal and powered the Holly Works and machines there along with the massive Holly and Gaskill hydraulic pumps.  The tour has you enter the tunnels which were actually the exit shoots for the plant. They are lined in iron plate at this point.
