Source Wikipedia: The present tower was built in 1720-21 by Trinity House, and was intended to work in conjunction with Walton Hall Tower to guide vessels through the Goldmer Gap. Towers at Naze and at Walton Hall are marked on a map of 1673 by Richard Blome, which in turn was based on a maps drawn up in the late 1500s. The present Naze Tower therefore replaced an earlier construction at a similar location. It was of particular benefit to ships using the nearby port of Harwich. Both the current Naze Tower and its predecessor had beacons or lamps lit at the top, providing an early form of lighthouse.
