Bryn Hafod-y-wern, Llanllechid

Information

The quarry was operated by the Pennant family from the 1780s. The lease passed out of the hands of the Penrhyn estate in the 1820s and the Royal Bangor Slate Company, established in London in 1845, later took over. Plans to connect the quarry to the Chester-Holyhead railway at Abergwyngregyn came to nothing, and the quarry was also affected by industrial unrest in the 1880s. Water to power the quarry came from Cwm Caseg via a leat five miles long. The water supply was cut off in 1889.

The hazardous flooded quarry pit is 50m deep and contains dumped unexploded World War II bombs and barbed wire. It is also the grave of a diver who died there in the 1970s.

  1. Very nice pic of the pit and comprehensive history. AJR’s Slate Gazetteer mentions the owner’s house still in habited condition, did you see that? Looks like a good site for a mooch!

    • If that is Bryn Hall (right next to the quarry), then yes I did. It used to be a Youth Hostel for a while, but is now a private residence.

      • I’ve just seen your posting of last March about Bryn Hall, nr Llanllechid. I stayed there once when it was a Youth Hostel in the late 1950s. It was run by a distant relative, a woman on her own but whose name now escapes me. I’ve seen the Hostel of those days referred to in one account as ‘cheerless’, which I’m afraid is pretty much how I found it, more or less. I wonder what the warden’s name was. I remember the tap water sometimes ran blue, from the slate.

  2. [...] Until 1889 water from here was carried by a leat five miles long to supply power to Bryn Hafod-y-wern Slate Quarry. [...]

  3. I always thought the distance of the leat which originates at afon wen was 8 miles and not 5 miles as you state???

    • I was born at Bryn Hall in 1960 when it was a Youth Hostel and my parents were the wardens. I remember my father telling me that he once threw a 1914-18 WW1 Colt revolver and ammunition into the quarry when ‘Silent Ellis’, the local bobby’, was chasing around for undisclosed firearms. I was last there to scatter his ashes around the O.S, triangle on top of Moel Wnion as requested by him.
