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.

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]
