Pictured here on the remote Cliffe Marshes are the remains of buildings used in the manufacture of explosives. Established as the Gunpowder Works in 1892 by Hay, Merricks and Company, gunpowder makers of Roslin, Scotland, it was eventually acquired by Curtis's and Harvey of Hounslow, who operated the site before it eventually closed in 1921, due to the downturn in the explosive market at the end of the Great War. Interestingly I read on the Cliffe History page, that between 1904 and 1921, 21 people were killed whilst working here and a further 38 suffered injuries. Along with other notable Kent gunpowder works disasters, it seems to me that making explosives in those days was not an industry you would want to be in.
