The Glynrhonwy quarries (also known as the Glyn-Rhonwy quarries) were two adjacent quarries in the Glynrhonwy area, north-west of Llanberis, in Carnarvonshire (now Gwynedd), Wales.

They were:

  • Upper Glynrhonwy quarry, known locally as "Glyn Ganol" or "Middle Glyn", which operated from 1861 to 1930,[1] and
  • Lower Glynrhonwy quarry, known locally as "Captain Taylor's Quarry", which operated from the early 1700s to 25 January 1930.[2]

The quarries operated internal railways of 2 ft (610 mm) gauge and were served by Glynrhonwy Siding off the LNWR's Caernarfon to Llanberis branch.[3][4]

Lower Glynrhonwy was acquired by the Air Ministry in 1939 for munitions storage. It occupied the site until 1961.[5] During the Second World War the site generated two extra trains per day on some occasions.[6] The railway siding was taken out of use on 18 December 1956.[7]

A 100 MW pumped storage project, marketed as a "quarry battery", received approval in 2017 and as at 2019 had reached the "detailed engineering design" stage.[8][9]
