Norham Castle (sometimes Nornam) is a castle in Northumberland, England, overlooking the River Tweed, on the border between England and Scotland. It is a Grade I listed building and a Scheduled Ancient Monument. The castle saw much action during the wars between England and Scotland. Early history The castle was founded when Ranulf Flambard, Bishop of Durham from 1099 to 1128, gave orders for its construction in 1121, in order to protect the property of the bishopric in north Northumberland, from incursions by the Scots. In 1136 David I of Scotland invaded Northumberland and captured the castle. It was soon handed back to the bishopric, but was captured again in 1138 during another invasion. This time, the structure of the castle was substantially damaged. It remained derelict until Hugh de Puiset, Bishop of Durham from 1153 to 1195, had the castle rebuilt. The work was probably directed by Richard of Wolviston, who was the bishop's architect. In 1174 Hugh de Puiset supported the rebels in a revolt against Henry II, during which the Scottish king, William the Lion invaded Northumberland. The rebels were defeated and as a result, Bishop Hugh was forced to relinquish Norham Castle to the crown. The castle was administered by a constable appointed by the crown and garrisoned by royal soldiers. This continued until 1197, two years after Hugh's death, when it was restored to his successor, Philip of Poitou. The latter showed himself to be loyal to King John. When Philip died in 1208 the castle reverted to royal control. Thirteenth century In 1209 the castle accommodated both King John and William the Lion, on an occasion when William did homage for his English lands to the English king. Between 1208 and 1211, King John maintained the castle defences in good order and provided a strong garrison. The strong defences were needed in 1215, when Alexander II of Scotland, son of William the Lion, besieged the castle for forty days without success. In 1217 the castle was once again restored to the bishopric of Durham. Edward I, known as “Hammer of the Scots”, visited the castle more than once. He did so in 1292 when John Balliol, King of Scotland did homage to him there. In 1296 Edward invaded Scotland, and during his campaign, his queen, Marguerite of France, remained at Norham Castle.
