Located at the Cefn Coed Colliery Museum in the Dulais Valley, on the A4109 two miles north of Aberdulais.

Cefn Coed Colliery was sunk in 1926-7 at that time being the deepest anthracite mine in the world with two shafts over 732m deep. The colliery began production of high-quality anthracite in 1930, employed over 900 men in 1945 and closed in 1968. The site remained in use in association with the Blaenant Drift Mine in the valley floor to the south, which was driven in the 1960s and closed in 1990. The Cefn Coed Colliery Museum was established in 1978 and has within its area at the side of the site several important monuments, including the colliery’s original steam boilerhouse, chimney, compressor house, electrical generating house and the winding house of No 2 shaft with the original steam winding engines.  

Colliery headframe, one of two original to the establishment of the colliery in 1926-7 and constructed of steel lattice girders with four vertical supports and two bracing buttresses extending from the head of the tower to the ground on the winding engine side. Each support has a brick plinth at ground level. The lattice girders are joined by rivetted plates. Both structures are some 18m high, with winding sheaves still in place at their tops, and form considerable landmarks in the valley. Both shafts have been capped with steel joists fixed in concrete and metal plate covers. No 2 headframe is the more southerly, and tops the downcast shaft. This was the headframe operated by the contemporaneous steam engine preserved and displayed in the adjacent museum. The structure is entirely open as ventilation control was not required. The frame has been out of use for many years and is in poorer condition, but no significant addition or subtraction seems to have been made since its construction in 1926.  

 

Listed at II* as the only surviving pre-war headframes in the anthracite coalfield, and one of only two sets of the once widespread lattice girder construction left anywhere in South Wales. They have important group value in relation to the adjacent preserved buildings of the Cefn Coed Colliery Museum, forming the principal landmarks of the site as a whole.
