The Pre-Norman features discovered are both defensive and settlement.
Extensive evidence of an early defense system and of a strong earthen rampart, held together with limestone boulders and protected by a deep ditch, show that King John’s Castle was built on an existing fortification.
King John’s Castle retains many of the pioneering features, which made its construction unique for the day. Its massive gate house, battlements and corner towers await your exploration while the armoury and its contents remain as evidence of its turbulent history
