During the summer 2016 we carried out evaluation digs for two hydro-electric projects in Breconshire, near Crai and Llangattock. Both included digging across old tramway beds. The Llangattock project also included excavating an old wall next to the site of Cwm, a farm which was abandoned some 150 years ago. This produced pottery of 18th and 19th century date, as well as small flakes of lead which may have been waste from the making of shotgun pellets.
