In depth
The fuller history
The quarry named Nant Gwrtheyrn opened in 1861, and was serviced by a village called Porth y Nant, on the site of the current language centre. Nant Gwrtheyrn produced setts, stone blocks used for road surfacing. The community lived an isolated existence, with product shipped and goods shipped out mainly via the Irish Sea, resulting in limited contact with the outside world. The quarry closed early in World War II, partly due to a drop in demand and also to transport difficulties.
