Pen yr allt is better described as a large set of workings working a N-S lode. These mostly consisted of many adits & open stopes. Some shafts were sunk which lead into more complex workings, but these shafts have been filled in. A large area of spoil on the surface mark the location of Pen-yr-allt.
