Located immediately to the south of the eastern slab mill at Felin Fawr Slate Works.  

Industrial  

 

Dating from 1832, the foundry is one of the earliest buildings at the Felin Fawr Slate Works, which complex was formerly the principal slate and slab manufacturing yard for the Penrhyn Slate Quarry, one of the most productive in Wales. The foundry chimney has been demolished.  

Tall rectangular plan building, aligned roughly north-south. Coursed and dressed slate slab construction with granite quoins and gable-ended slate roof with stone kneelers; circular brace plates. Four 3-light timber windows with long slate lintels and cills on western side. South gable end formerly with external, tapering square stack in orange brickwork, the remaining brickwork of which rises above the brickwork of a round-arched opening; infilled doorway to right. Similar arch to north gable end which also has a small lean-to roofed section in north-west angle. Eastern roof slope with rooflights, wall below concealed by adjoining fitting and repair shop. Lower gabled, slated range with small brick stack runs at right-angles to west at southern end, against which is an open 3-bay slate-roofed lean-to on cast-iron columns, the eastern bay of which overlaps the southern gable end of the main building.  

Interior retains massive wooden trusses with braced timbers on cast-iron brackets formerly supporting a travelling crane.  

Included as one of the earliest surviving structures at the exceptional group of buildings comprising the Felin Fawr Slate Works.
