The big Gasholder was built in 1902. During commissioning of the gasholder the sealing membrane is set into an operating condition. It is also known as Brisbane Gas Company Gasworks and Newstead Gasworks No.2 gasholder. It is notable as the site for the first arc-welded gasholder in the world. Throughout the winter months, Sheepscar is notable for its large gasholder. The second and older spiral guided gasholder was removed some years ago. Sheffield landmarks such as the Park Hill Flats and Neepsend Gasholder are also seen. The Troy gasholder was a telescoping two-lift type. The gas would then be ready for distribution, and pass into a gasholder for storage. A dry-seal Wiggins gasholder is a device designed to hold gas. The original gasholder was removed from the first building in 1919. In 1937, gasholder No.2 was fitted with a new crown of riveted steel plate. By 1965, No.1 gasholder in Ann Street had been dismantled. In the 1930s the gasholder was removed and sold as scrap metal. For these communities, the gasholder (remnants) and guide framing was and is an important landmark.
