Norham Castle overlooks the River Tweed near Berwick-upon-Tweed, a strategic fortress established in 1121 by Bishop Ranulph Flambard as the administrative center for Durham's northern territories. The castle's imposing 12th-century keep, rebuilt on a grand scale by Bishop Puiset, stands as a testament to medieval power and prestige. Over its 500 years of military significance, Norham was besieged at least 13 times, including a nearly year-long siege by Robert Bruce, and played host to Edward I during his arbitration over the Scottish throne in 1291. The castle's vulnerability to cannon fire became evident in 1513 when James IV captured it. English Heritage now preserves the dramatic ruins, which remain symbols of the castle's crucial role in border defense.
