Statement of Interest

A Group with Prestongrange Colliery, Hoffman Kiln, and Prestongrange Colliery, Old Generating House (see separate listings). Monks from Newbattle Abbey originally mined for coal here as far back as the twelfth century. This was the start of the area's connection with coalmining, and the first shaft of Prestongrange's last mine was sunk in 1830. The beam engine was built by Harvey and Company of Hoyle in Cornwall, and was shipped to Scotland and erected in 1874. It pumped water out of the pit, in three stages, at 2955 litres a minute. The mine was eventually closed in 1963, and after abandonment and partial clearing it was saved and became part of the Scottish Mining Museum. The only other beam engine surviving in Scotland is the Devon Colliery Beam Engine House, Clackmannan (Neilson & Co., Glasgow, 1865).
