Castle of St. John

The Castle of St John stands in the centre of Stranraer, a town in Dumfries and Galloway in southwest Scotland. Built around 1510 by the Adairs of Kilhilt, it is an early 16th-century L-plan tower house. The castle has served many purposes over the centuries, including as a home, a court, a police station and a military garrison. During the 1680s, it was used as a garrison during the Killing Times of Covenanter persecution. In the Victorian era, the castle was modified to serve as a prison. The castle’s varied history makes it an interesting place to visit. It was used as an ARP base during the Second World War and later refurbished in the late 1980s. Now, it operates as a museum, offering visitors a glimpse into its past roles. The Adairs of Kilhilt, originally from Ireland, built the castle as their family home. Its use as a prison in the 19th century adds another layer to its story. Inside, visitors find a museum with displays about the castle’s many uses. The L-plan design of the tower house is still visible, with its distinctive shape. The refurbished rooms show how the castle has changed over time. Outside, the castle stands in the heart of Stranraer, close to other historic buildings. The surrounding area offers views of the town and its maritime heritage.
