Wihtwara was the kingdom founded on the Isle of Wight, a 147-square-mile (380 km2) island off the south coast of England, during the Anglo-Saxon settlement of Britain. The name was derived from the Jutish name Wihtwara. Its capital was a fort named Wihtwarasburgh. It has been suggested that the modern-day village of Carisbrooke was built on top of Wihtwarasburgh due to the fact that they share their location. It has also been suggested that Wihtwarasburgh was built on top of a pre-existing Roman fort, but this has not been proven.
