Between 1832 and 1932, Blaendare Brick Works used to operate in pits on the Upper Race in Blaendare near Pontypool, Wales. These are more recently known as the Glyn Pits.
The Works mined for coal and fire clay and one of the mine entrances and collection points, the Lary Gorse Bush Level, was very small, and one of the only levels where donkeys were used instead of horses because of limited heights. The donkeys would pull the trams into the shafts and back out.
