Eynsford Castle is one of the most complete Norman castles in England, located close to the village of Eynsford. Built in 1088, ransacked in the 14th Century it fell into decay and is now in the care of English Heritage and open to the public. For years it was used as dog kennels by the Hart-Dyke family of nearby Lullingstone.
Surviving fragments include sections of the curtain wall, some up to 30 feet in height, including evidence of the latrines, and buildings within the walls.
