Castle of St John
10 minute walk from Stranraer station · South West

The Castle of St John, also known as Stranraer Castle, is a historic L-plan tower house located in the centre of Stranraer. Built around 1510 by the Adairs of Kilhilt, this early 16th-century landmark stands as a significant piece of southwest Scotland’s heritage.
The castle boasts a diverse history, having served as a home, a court, and a military garrison during the "Killing Times" of the 1680s. Visitors can explore a building that has functioned as a Victorian prison, a police station, and a Second World War ARP base. Now a museum, the refurbished castle offers an informative look into centuries of local history.
