The Women Who Ruled Castles
Popular history tends to paint medieval women as passive figures - decorative presences gazing from tower windows while men did the real work. The reality was radically different. Women ran castles, managed vast estates, defended walls during sieges, negotiated treaties, and wielded political power that shaped the course of nations.
Here are some of the most remarkable women who ruled castles - and what their stories tell us about the true nature of medieval power.
The Chatelaine: Lady of the Castle
In the medieval world, the lady of the castle (the chatelaine) held enormous responsibility. When her husband was away - which was often, given the demands of war, court, and diplomacy - she became the sole authority. This wasn't just domestic management. It was governance.
Financial Management
The lady oversaw all household accounts, collected rents, managed agricultural production, and ensured the estate remained financially viable. This required sophisticated accounting skills.
Justice
In the lord's absence, the lady held court and administered justice - settling disputes, imposing fines, and ensuring order across the estate.
Healthcare
Noble women were expected to know herbal medicine and basic surgery. They tended to the sick and injured within the castle and often in the wider community.
Diplomacy
Marriages were political alliances, and noble women served as diplomatic links between families and kingdoms. Their correspondence networks were vital channels of information.
Women Who Defended the Walls
When castles came under attack and the lord was absent, it fell to the lady to organize the defense. Several did so with extraordinary courage and skill:
Nicola de la Haye (c.1150-1230)
Hereditary castellan of Lincoln Castle, Nicola defended it twice - once during a rebellion against King John and again during the First Barons' War. At the Battle of Lincoln in 1217, she held the castle against a French-backed siege. She was in her sixties. She continued to serve as sheriff of Lincolnshire afterward, one of only two women ever to hold that office.
Black Agnes of Dunbar (1312-1369)
When the Earl of Salisbury besieged Dunbar Castle in 1338, Agnes, Countess of Dunbar, personally led the defense. She famously had her maids dust the battlements after each bombardment - a theatrical gesture of contempt. After five months, Salisbury withdrew. Agnes had defended her castle without losing a single section of wall.
Lady Brilliana Harley (1598-1643)
During the English Civil War, Brilliana defended Brampton Bryan Castle against Royalist forces for three months while her husband was away in Parliament. Her letters during the siege reveal a woman of remarkable courage, faith, and tactical intelligence. She died shortly after the siege was lifted, likely from the strain.
Jeanne de Clisson (1300-1359)
After the French king executed her husband, Jeanne sold her estates, raised an army, and attacked French garrisons across Brittany. She then took to the sea as a pirate, becoming "The Lioness of Brittany," raiding French ships for 13 years. Her castles in Brittany served as bases for her war of vengeance.
Queens and Power Brokers
Eleanor of Aquitaine (1122-1204)
Queen of France, then Queen of England, Eleanor was one of the most powerful women in medieval Europe. She ruled Aquitaine in her own right, led troops on crusade, governed England as regent, and raised a rebellion against her own husband, Henry II. Her court at Poitiers was a center of culture and learning.
Isabella of Castile (1451-1504)
Isabella didn't just live in castles - she conquered them. As Queen of Castile, she personally organized military campaigns, reformed the kingdom's administration, and funded Columbus's voyage. The Alcazar of Segovia, where she was crowned, remains one of Spain's most iconic castles.
Margaret Beaufort (1443-1509)
Mother of Henry VII, Margaret was the political mastermind behind the Tudor dynasty. She managed a vast network of castles and estates, funded educational institutions (including Christ's College and St John's College, Cambridge), and wielded influence that outlasted many kings.
A corrective to the record: The traditional focus on male military figures in castle history obscures the reality that women were central to the functioning of the castle system. Without their management, diplomacy, and - when necessary - military leadership, the castle as an institution could not have operated.
Seeing Castles Differently
Next time you visit a castle, think about the women who lived and worked there. Look at the solar (the private chambers), the kitchens, the herb gardens, the chapels - these were the spaces where much of the real power was exercised. The great hall was a stage; the rooms behind it were where the decisions were made.
