Lettergesh National School is situated in Renvyle in Connemara on a picturesque elevated sloping site overlooking the sea expanse from Mannin Bay to the south in County Galway and Clew Bay to the North in County Mayo as well as the islands to the south-west of Clew Bay.
The first national school was opened in this area under the patronage of Mitchell Henry in 1868 and the current school building opened in 1976, directly across the road from the old school building.
The original school was built to educate the children of the estate labourers. There is a mountain track from the school to Kylemore Abbey, the original home of Mitchell Henry, and forefathers of many of the current pupils would have worked on the estate. The current two classroom building remains much the same as when it was built.
The school has two mainstream class teachers and a shared special educational needs teacher.
