 Moving counter-clockwise around the curtain wall from the north-west, the rectangular Lilburn Tower looks out across Embleton beach.The tower was named after an early castle constable, John de Lilburn, but may have been built under Thomas of Lancaster; it was intended as a high-status residence, 59-foot (18 m) high, square with thick walls, with a guardroom for soldiers on the ground floor.The rectangular towers at Dunstanburgh reflects the local tradition in Northumberland, and are similar to those at nearby Alnwick.
