Wynnstay Colliery fan house

Wynnstay Colliery was sunk by the New British Iron Company starting in 1856.By 1896 the ownership lay with Wynnstay Collieries Co. Ltd., Ruabon, and this company erected a 22ft Walker ventilation fan in 1902. Although the colliery closed in 1927 there are extensive remains to be found on the site including the winding enginehouse (www.ipernity.com/doc/302581/35388203), and this building that housed the fan.
