This is the old coal gasification plant at GasWorks Park in Seattle. It was in operation from 1908-1958, owned by the Seattle Gas Lighting Company. Amazing to think gas lighting was still in use up to 1958.
The image is a little bit noisy because I used a 30 second exposure at 1600 ASA to get this image at night. I have nice crisp clear day images of this plant but I liked the dark ominous tone the night image provides.
