Schiehallion (/ʃiːˈhæli.ən/; Scottish Gaelic: Sìth Chailleann, IPA: [ʃiˈxaʎən̪ˠ]) is a prominent cone-shaped mountain in the Breadalbane region of the Scottish Highlands, in the county of Perthshire. It rises to 1,083 metres (3,553 ft) and is classed as a Munro. Schiehallion has a rich botanical life, interesting archaeology, and a unique place in scientific history for an 18th-century experiment in "weighing the Earth". It is near the centre of mainland Scotland. The mountain's popularity amongst walkers led to erosion on its footpath and extensive repairs were undertaken in 2001.
