Knockmore (from Irish Cnoc Mór 'big hill') is an upland area and townland situated in County Fermanagh, Northern Ireland outside the village of Derrygonnelly, in the historical barony of Magheraboy.
[3] The flora and fauna in this area are largely as a result of the underlying limestone and sandstone geology, consisting of upland heath mixed with calcareous grassland.
[1] The area is especially noted for the appearance of Irish eyebright (Euphrasia salisburgensis), which is considered a priority species in Northern Ireland.
[3] Among the other caves studied on Knockmore is Gillie's Hole, located part-way up the southern cliff face of the summit.
[6] Named for its 18th-century occupants, reportedly a young couple ostracised by their families, the cave was discovered by Wakeman (1870) to contain further inscriptions of ancient celtic origin.
