These eerie images capture the dramatic dereliction and decay of a Doncaster factory which once employed hundreds of workers.
The stark collection of photographs show the former Pilkington Glass factory at Kirk Sandall which during its heyday was one of the town's biggest employers.
Now the building which once resounded to the sound of glass making is silent and abandoned - strewn with weeds and being reclaimed by both nature and vandals.
Graffiti has been daubed on walls and machines which once hummed and operated around the clock are now rusting and crumbling and being battered by the elements.
Video of the site has also emerged and been shared on video sharing website YouTube.
The pictures have been shared on Facebook in groups devoted to "urbex" - urban exploration, or taking a glimpse inside abandoned buildings, factories, shops and places of entertainment.
The factory closed in 2008 with the loss of more than 100 jobs.
However, during its 80 years in business, the works employed hundreds more workers and Doncaster was known nationally and globally as a worldwide centre of glass making.
The company was founded in 1826 as a partnership between members of the Pilkington and Greenall families and based in St Helens, Lancashire.
During the 1960s and 1970s, Pilkington opened plants in several countries including Argentina, Australia, Canada and Sweden. The firm was taken over by Japanese company NSG in 2006.
The person who took the photographs has given us permission to reproduce them but has asked not to be named. The compiler of the video and the photographer are not connected.
Urbex fans can face physical danger from exploring abandoned buildings as well as the possibility of arrest and punishment for trespass.
