The Royal Burgh of Sanquhar is a town in Dumfries and Galloway, on the River Nith's northern bank. It lies north of Thornhill and west of Moffat along the A76 Kilmarnock to Dumfries road, with direct train services to both towns as well as Carlisle, Newcastle and Glasgow.
Sanquhar is notable for its tiny post office (established in 1712), claimed to be the oldest working post office in the world. It also hosts the world’s oldest curling society, formed in 1774 with sixty members. James Brown, who wrote an important history of the town, is credited with writing the rules universally used for the sport.
