A small settlement on the Meggat Water in Dumfries and Galloway, Jamestown lies 4½ miles (7 km) north of Bentpath. Named after the land-owner Sir James Johnstone of Westerhall (1726-94), a settlement was established here by the Westerhall Mining Company in the 1790s for miners working at the short-lived Louisa mine, which extracted the element antimony that had been discovered here.
The noted engineer Thomas Telford was born at the neighbouring Glendinning Farm in 1757.
