Winding Engine House, Newbury Colliery

The Winding Engine House at Newbury Colliery, built around 1860, is a two-storey structure made of roughly coursed dressed limestone, featuring hammer-dressed architraves and quoins, topped with a gabled corrugated iron roof. The building has a rectangular plan, with a bob wall in the gable end that includes a corrugated iron panel over an opening and a keyed semi-circular arch leading to the basement level. The return and rear elevations also display keyed semi-circular arched openings above similar arched openings at the basement level. Although the interior was not inspected, this engine house is significant as it relates to the expansion of coal production at the site, which began in 1799, particularly following the sinking and opening of the Mackintosh shaft in 1867. It is recognized as the best surviving example of an engine house from the Mendip area coalfields and holds national importance as a remnant of the coal industry.
