Clun ˈklʌn (Colunwy) is a town in south west Shropshire, England, and the Shropshire Hills Area of Outstanding Natural Beauty. The 2011 census recorded 680 people living in the town. Research by the Campaign for the Protection of Rural England suggests that Clun is one of the most tranquil locations in England. Clun takes its name from the river upon whose banks it stands. Deriving from the Welsh Colunwy, it shares its very early Brythonic root with the two rivers Colne, in Lancashire and Essex, each of which has a town of the same name on its banks. Clun grew up around the site of an Anglo-Saxon church towards the end of the 7th century AD. However, in the surrounding area there was a scattered population at least as early as the Neolithic period, about 5000 years ago. Clun was on the historic drove road where flocks and herds were driven from Wales to the markets in the Midlands and London. At the time of the Norman Conquest Clun formed part of the extensive lands of Eadric the Wild, who led a revolt against King William I, whereon his lands were confiscated and given to Roger de Montgomery who was created Earl of Shrewsbury. Roger in turn granted 27 manors, of which Clun was the largest, to Picot de Say. These lands constituted a single Marcher Lordship which became known as the Barony of Clun. The de Say family established Clun Castle. The 14th-century pack horse bridge that crosses the river connecting Saxon Clun to Norman Clun has given rise to a local saying: "whoever crosses Clun Bridge comes back sharper than he went". Clun Mill located to the north of the town is nicknamed the "malevolent mill" on account of numerous deaths having been recorded there and occupants disappearing after purchasing it. Last used around 1920, it opened as a youth hostel in 1932. The town's name is taken from that of the River Clun (Colunwy), which flows from west to east through the settlement. The Clun Valley is dominated by agriculture, though some areas of woodland remain. The River Unk joins the Clun just to the west of the town.
