Slate quarries in the landscape and their names
, 8 October 2026
The National Slate Museum is keen to celebrate the wealth of names for slate quarries scattered throughout Wales by carving their names into a slate path which will lead to the gateway of the refurbished Museum. Anyone who explores the many corners of Wales will easily notice the remains of the huge effort made by previous generations to dig and extract slate rock from the ground and transform it into slates for various uses. Some of these remains can be very obvious since the quarrymen reshaped the landscape by blasting the rock and pouring waste into massive tips. And yet the remains of some of the quarries are mere ripples on the face of the earth since they weren’t worked for long enough to produce much waste nor create the need for numerous holes, addits and a transport system. Whatever the size and substance of the physical remains another clue can point to the presence of a quarry and that is its name.
Most of the names are Welsh and they frequently originate from a nearby landscape feature e.g. Ffynnon y Gog – cuckoo spring, Dŵr Oer – cold water, Pompren – wooden bridge a Rhiw Gwreiddyn – hill of the root. Some of them have been named after a person such as Doctor Hughes, Chwarel Gethin – Gethin’s quarry, Mathew’s, Palmerston’s, Vivian and Hollands. Several of the names simply follow the name of the location or area where they reside such as Tal y Fan, Nantlle Vale, Hafod y Llan, Garreg Fawr and Deeside. It may be difficult to trace exactly why some quarries have been given a specific name, but the name itself is so well known that it is synonymous with a slate quarry even without the prefix ‘chwarel’ or quarry. We could refer to Dorothea, Glynrhonwy, Llechwedd, Prince of Wales and Alexandra in this regard.
More than anything, the wealth of quarry names present in various corners of Wales is testament to the sweat and labour expended by men to produce and export slate to the four corners of the world. Over the years historians and experts have recorded the majority of the quarries in various papers and books. The Slate Museum redevelopment project is keen to celebrate this wealth by carving as many names as possible into a slate path which will lead visitors to the gateway. After poring over various sources Museum staff have gathered a list of 196 names which include names from the area of the World Heritage Site in Northwest Wales in addition to Denbighshire, Pembrokeshire, Radnorshire and Carmarthenshire. However, we need to ensure that the path is as representative and comprehensive as possible and so we are calling on local knowledgeable people the length and breadth of Wales to contribute names of lesser-known quarries here:
