Stonehouse Brick and Tile Company
This was one of the major brick manufacturers in the area. They opened their works on a site just north of Stonehouse (Great Western) railway station in about 1890. The brickworks chimney was the largest chimney in Gloucestershire (202 feet) until it was demolished in 1965. The works closed soon after in 1968.
A history of the company was published in 1997 and may be downloaded here as a PDF file (350kB).
