If it was not for the dangers of unstable ground, inflammable and asphyxiating underground gases, the Ironbridge Gorge would be a paradise for the industrial archaeologist with spelaeological and mining interests. In a two mile length of Gorge there are opportunities for scaling limestone shafts, crawling through tenuous, long-abandoned tunnels and the prospects of a 'find' on every trip that would make the surface archaeologist green with envy. This short article is an attempt to bring together some of the results of over twenty years underground research in the Gorge by the writer, and other members of the Shropshire Mining Club. More detail is available in the publications of the Club and in the other papers listed. It is stressed that on no account should any workings be approached other than through format channels and all underground workings located in the Gorge should be treated with respect.
