These 2 bottle kilns in Longton were built in the late 19th century as part of the Commerce Works pottery. The pottery was run by the Chetham family from 1796 - 1869 and then taken over by H.J Aynsley in 1873. Final closure came in the 1990s and the site has stood derelict since. The building is listed Grade II but I doubt that will save it.
