Excavations at Llangorse Quarry began about 200 years ago when local labourers were employed to mine building stone and roofing tiles for nearby villages. 
The stone, with its distinctive shades of red and green and its resistance to erosion, was found to be ideal for this purpose.
Over time use of the quarry reduced until closure, until in 1982 when the quarry reopened and work resumed after a dormant period of almost seventy years. Today the old workings can be found surrounding the present day quarry and the quarry, with its stunning views over the nearby Llangorse lake and its proximity to the world renown Brecon Beacons National Park, continues to expand on its success.
Being a wholly family-run business we are dedicated to producing the highest quality products; as a result our stone has featured everywhere from the Royal Welsh Agricultural Show
to some of the latest buildings and features throughout the National Park. Meanwhile we continue to provide supplies such as draining stone, scalpings and infill for lower profile agricultural and building projects.
In addition to its industrial use, the quarry is the subject of continuous research by a Welsh university where its 400 – 425 million year old Devonian sandstone is analysed through the use of bore holes and sedimentary studies.
