Crowtrees Colliery, Quarrington Hill, County Durham: Archaeological Building Recording (OASIS ID: archaeoe1-76298)

Archaeo-Environment Ltd were commissioned by the Crowtree Heritage Group to undertake an Archaeological Building Survey of the standing remains associated with the former Crowtrees Colliery. These included a large concrete and stone structure towards the centre of the site thought to be the winding engine house, and a smaller masonry structure to the NE of the capped pit head. The engine platform is constructed of large masonry blocks interspersed with layers of shuttered concrete, and this may have been to absorb and redistribute some of the vibrations from the engine originally mounted on top of the platform. The second structure to the east of the capped pit head it thought to have been a vertical pumping engine. The standing building remains at Crowtrees are considered to be of regional if not national significance as they are rare examples of a 19th century winding house and associated features.
