The Gas Works

In England, it is common to see huge circular structures. For many years, I didn't have any idea what these were for. I've learned that they are used to contain inflatable gas bags that contain natural gas. Because this picture was taken in June, the bags are almost completely deflated (there is not much demand for natural gas in June). In the winter, the inflatable bags are much larger. The water in the foreground is Regents Canal.
