History+
The castle's origins date back to 1550, when it was built during a period of conflict between England and Scotland and the threat of Viking raids. Building materials were sourced from the nearby Lindisfarne Priory. Between 1570 and 1572, the fortification on Beblowe Crag, the island's highest point, was further expanded. With the unification of the English and Scottish crowns under James I, the castle's strategic importance diminished. In the 18th century, it was briefly occupied by Jacobite rebels but quickly recaptured.
