L © The Bonau Cabbage Patch Pant Hywel Colliery Pant Hywel Mine started its life as a coal mine, and in its latter years,  worked fire clay. Hidden away, its once ornate entrance guided  underground by a cast iron bridge crossing a small river is now nothing  more than a sealed tunnel way that leads into the ground. The remains  of the bridge lay in the river. The Coal Authority have sealed the access  point. Pant Hywel level was opened in the 1890's to work pillars left in the  Hughes or Pwll Big Vein that had previously been worked by Stradey  Colliery. In the early years the mine was owned by David Jones and  later it passed into the hands of D. J. Griffiths. Just before Christmas 1912 Eleazer Evans was killed by a fall of ground.  At the inquest held at Libanus Chapel it was stated that there were 12  men employed at the mine. From a list 1923, there were 8 men employed, producing from the Big  Vein. The drift entrance was accessed by a cast iron bridge across the river,  Afon Cwmmawr which flows into Carmerthen Bay only a short distance  down stream.   Pant Hywel was closed during the early 1930's for coal production but  was worked until the early 1960's to provide fire clay for the Pwll  brickworks.  Pant Hywel Iron Dram Bridge crossing Avon Cwmmawr
