Carisbrooke Castle Built
1100
Context: Norman castle building across England established military control over the conquered population and provided administrative centres for the new feudal order.
Carisbrooke Castle is the Isle of Wight's most important historical monument, a fortification that has served continuously as a seat of power for nearly a thousand years. The site has been occupied since at least the Saxon period, when a burh, or fortified settlement, was established on the chalk ridge above the village of Carisbrooke. But the castle as a stone structure dates from the Norman period, with the principal building works carried out in the late eleventh and early twelfth centuries.
The Norman keep, a rectangular stone tower standing on a high motte, was built around 1100, probably on the orders of the de Redvers family, who held the lordship of the island at the time. The keep commanded views across the island in every direction and served both as a military strongpoint and as the administrative centre from which the lord governed. The surrounding curtain walls, enclosing a large bailey, were added and strengthened over the following decades. By the mid-twelfth century, Carisbrooke was one of the most formidable castles in southern England.
The castle's military history is long. During the civil war between Stephen and Matilda in the 1130s and 1140s, it was held for Matilda by Baldwin de Redvers, who was eventually starved into surrender when the castle's well ran dry. This vulnerability was addressed: the well that can still be seen today, with its famous donkey-powered wheel, was dug to a depth of 161 feet to ensure that the garrison would never again lack water. The well house, though rebuilt in later centuries, remains one of the castle's most distinctive features, and donkeys still demonstrate the mechanism for visitors.
In 1377, when a major French raiding force attacked the island, the castle served as the refuge for the population of Newport and the surrounding area. The French burned much of the island's coastal settlements but could not take Carisbrooke. The experience prompted significant investment in the castle's defences, and further improvements were made under the Tudors, when the threat from France and Spain made coastal fortification a national priority.
The most dramatic transformation came in the 1590s, when the Elizabethan engineer Federigo Giambelli designed a new outer ring of artillery fortifications, turning the medieval castle into a modern defensive work capable of resisting cannon fire. These arrowhead-shaped bastions, built of earth and stone, are among the best-preserved Elizabethan fortifications in England and give the castle its distinctive plan.
Carisbrooke's most famous episode came in 1647-1648, when Charles I was imprisoned here during the English Civil War. The castle's role as a royal prison is detailed elsewhere in this timeline, but the physical fabric of the castle preserves the memory: the window through which the king attempted to escape, the rooms he occupied, and the bowling green where he took exercise are all still identifiable.
The castle continued in military use into the eighteenth century, when it served as a barracks and later housed prisoners of war during the Napoleonic Wars. Princess Beatrice, Queen Victoria's youngest daughter, lived in the castle as Governor of the Isle of Wight from 1896 until her death in 1944. Today, managed by English Heritage, Carisbrooke Castle is the island's pre-eminent historical attraction, its layers of history visible in every wall and courtyard.
Impact
Gave the Isle of Wight a permanent centre of military and administrative power that served continuously for nearly a millennium, from Norman keep to Elizabethan artillery fort to royal prison.
