Cefn Coed Colliery, No. 1 Shaft Headframe

Cefn Coed Colliery's No. 1 Shaft Headframe is a colliery headframe built between 1926 and 1927. It is made of steel lattice girders supported by four vertical posts and two bracing buttresses that extend from the top of the tower to the ground on the winding engine side. Each support rests on a brick plinth at ground level, and the lattice girders are connected by rivetted plates. The headframe stands approximately 18 meters high, with winding sheaves still present at the top, making it a notable landmark in the valley. Both shafts have been capped with steel joists fixed in concrete and metal plate covers.

No. 1 headframe is the more northerly of the two and is positioned over the upcast shaft, which is linked underground to a nearby fan house. The interior of the tower is enclosed with steel plates to manage ventilation, directing air down No. 2 shaft. The steel lattice structure is in good condition and was recently used to provide additional access to the Blaenant drift. Overall, the headframe retains much of its original appearance, with some modifications including a new steel staircase added on the east side, a new platform constructed at the sheaves level, and the removal of the topmost bracings.
