Book excerpt: Underground mine and quarry workings are to be found in all counties in England. This little-seen and often exciting world has workings that are different from each other in terms of what was extracted and how this was achieved. The archaeological evidence allows us to interpret what was being done and when this took place. Some places have impressive workings and these have such things as engine chambers, arched levels, deep shafts, underground canals, drainage soughs, and discarded equipment.0This book presents a detailed introduction to the underground mining and quarrying heritage in England. It reviews the many types of mineral and stone taken from the ground over several millennia and also looks at the wide range of archaeological remains that survive today and are accessible to those who venture underground. It is designed to illustrate the many and varied wonders to be found underground and give the reader ways forward should they wish to follow up their interest in particular types of extraction or what is present in their region.
