The Isle of Grain is the easternmost point of the Hoo Peninsula in the district of Medway in Kent. No longer an island, the Isle is almost all marshland and the Grain marshes are a major habitat for diverse wetland birds. The Isle constitutes a civil parish, which at the 2011 census had a population of 1,648, a net decrease of 83 people in 10 years.HistoryExtract from the Topographical Dictionary of Great Britain and Ireland by John Gorton, 1833: "GRAINE, ISLE OF, co. Kent'' "A parish in the Hundred of Hoo, lathe of Aylesford, opposite to Sheppey at the mouth of the Thames; it is about three miles and a half long, and two and a half broad and is formed by Yantlet Creek running from the Medway to the Thames. The Creek was filled up, and had a road across it for 40 years until 1823, when the Lord Mayor ordered it to be again reopened, so as to give about eight feet navigation for barges at spring tide; thus saving a distance of fourteen miles into the Medway, and avoiding the danger of going round by the Nore."The closure of the road caused considerable anger among the residents of the Island and it was later reopened. The goods route from the Medway Towns to the upper Thames Estuary was later shortened by the Thames and Medway Canal, although this route, too, has been abandoned.
