The largest and most successful of the Llanwrst mines. Originally opened in 1855 as the Gwydyr Park Consols and worked intermittently up to the 1940s. Reopened in 1950, Parc Mine produced more lead and zinc ore between 1953-57 than the whole of the Llanwrst area between 1848-1939. Closed 1958. Grid reference is for the portal of the number 3 adit, the main haulage level.
