Castle of St John The Castle of St John, a well-preserved 16th-century tower house, stands in the heart of Stranraer, Scotland. Originally built as a residence for the Adair family, the castle played a significant role in the region’s history, serving as both a defensive stronghold and a symbol of power. Unlike more rural castles, the Castle of St John was strategically positioned within a bustling town, offering control over local trade routes and maritime activities. Constructed with thick stone walls and a commanding tower, it was designed to withstand potential attacks while also providing accommodation for its noble occupants. Over the centuries, the castle saw varied uses, including a military garrison and a prison during the turbulent times of the Wars of the Three Kingdoms and the Jacobite risings. By the 19th century, it was repurposed as a jail before eventually becoming a historical site open to the public. Today, the Castle of St John is managed by Museums Galleries Scotland and offers visitors an immersive experience into its past. With interactive exhibits, well-preserved architecture, and insights into Stranraer’s history, the castle remains a fascinating destination for those exploring Scotland’s medieval and post-medieval heritage.
