Aberllefenni Slate Quarry is the collective name of three slate quarries, Foel Grochan (sometimes misspelt as Foel Crochan), Hen Chwarel and Ceunant Ddu, located in Aberllefenni, Gwynedd, North Wales. It was the longest continually operated slate mine in the world until its closure in 2003. Foel Grochan is the quarry on the eastern side of the valley, facing Ceunant Ddu and Hen Gloddfa on the west; all three were worked as a single concern throughout their history. Technically all three of these are mines, not quarries, since all rock extraction takes place underground, though they are often referred to as quarries.

Famous quotes containing the word quarry:
“Come see the north winds masonry.
Out of an unseen quarry evermore
Furnished with tile, the fierce artificer
Curves his white bastions with projected roof”
