The Barony of Strathaven was acquired in 1362 by Archibald the Grim, Lord of Galloway, by his marriage to Joanna, daughter to Maurice de Moravia, 1st Earl of Strathearn, great Moray heiress. The settlement within the lands of Strathaven became a Burgh of barony in 1450. It still retains its traditional character despite the growth of more modern housing. The centre of the town is occupied by the market square, formerly a grassed common, and still known as Common Green, or just ‘The Green’. Linking the town and the castle is the old ‘Boo Backit Brig’ (‘bow-backed bridge’), a small arched bridge. The Old Parish Church, with its landmark spire, was built in 1772, and was the place of worship of the Duke of Hamilton who maintained a shooting lodge at nearby Dungavel House.
