Cliffe is a village on the Hoo Peninsula in Kent, England, reached from the Medway Towns by a three-mile (4.8 km) journey along the B2000 road. Situated upon a low chalk escarpment overlooking the Thames marshes, Cliffe offers views of Southend-on-Sea and London. It forms part of the parish of Cliffe and Cliffe Woods in the borough of Medway. The population of the village is included in the civil parish of Cliffe and Cliffe Woods. In 774 Offa, King of Mercia, built a rustic wooden church dedicated to St Helen, a popular Mercian saint who was by legend the daughter of Coel ("Old King Cole") of Colchester. Cliffe is cited in early records as having been called Clive and Cliffe-at-Hoo.
