Slieve Snaght (Irish:Sliabh Sneachta, meaning 'snow mountain')[2] is amountain in the middle of theInishowen peninsula ofCounty Donegal,Ireland. It rises to a height of 615 metres (2,018 ft), making it the highest mountain in Inishowen,[2] and is one of the northernmost mountains of Ireland. It should not be confused with the mountain of the same name in the nearbyDerryveagh range. It includes the lesser summits of Slieve Main, Crocknamaddy and Damph.[2]
The mountain is said to be so named because snow lies on its summit until late May.[2] InCath Maige Tuired ("The Battle of Moytura"), a tale fromIrish mythology, Slieve Snaght is called one of the "twelve chief mountains" of Ireland.[3] There is a tradition of pilgrimage to the top of Slieve Snaght atLughnasa, and aholy well near the summit, calledTobar na Súl ("well of the eyes"), is said to cure blindness.[2]
In 1825, the summit was one of those used as a base for mapping Ireland as part of theOrdnance Survey'sPrincipal Triangulation. The surveyors, which includedThomas Drummond, camped on the summit and built a wall to shield themselves from the weather. Drummond's team shone alimelight from Slieve Snaght towardsThomas Colby's team onDivis 67 miles (108 km) away, the first time a limelight was used for surveying.[4]
