The Hoo Peninsula separates the estuaries of the rivers Thames and Medway. It is dominated by a line of sand and clay hills surrounded by an extensive area of marshland composed of alluvial silt; the name Hoo is the Old English word for high.
The Romans have been credited with the first two attempts at building a sea wall. The subsequent draining of the marshes had a two-fold benefit in that pastureland was created which supported sheep; and the indigent malaria bearing mosquito was deprived of their breeding grounds.
The area is rich in archaeology. Bronze Age implements and Jutish cemeteries have been found on the peninsula, and Roman pottery at Cooling. It was once the point of departure across the ancient Saxon fording point over the River Thames to Essex.
Much of the Peninsula lies in one of the Saxon divisions of England called 'hundreds': here it is the 'Hundred of Hoo'. In the interests of accuracy, the Hundred comprised the parishes and churches of Hoo St Werburgh, High Halstow, St Mary's Hoo, Allhallows and part of Stoke. The Isle of Grain, then a complete island, was in the Hundred of Gillingham; the remainder of the parish of Stoke was in the Hundred of Shamel. (Notes from The Hundred of Hoo (Ralph Arnold, Constable 1947))
William the Conqueror granted his half-brother, Odo, the large estate of Hoo.The marshlands are now part of two protected areas of land: the Thames Estuary and Marshlands and the Medway Estuary and Marshes. The Thames Estuary area covers the 15 miles (24 km) from Gravesend to the Isle of Grain; the Medway area 15 miles (24 km) from Rochester to the Isle of Grain: a total of 38 square miles (98 km˛) of marshlands.Both are considered as Sites of Special Scientific Interest ( SSSI) and Special Protected Areas (SPA). They include coastal grazing marsh, intertidal mudflats, saltmarsh and lagoons. On the line of hills lies the [Northwood Hill] National Nature Reserve.
The Rivers Thames and Medway were once joined by an ambitious project of construction in the form of the eight-mile long Thames & Medway Canal, the construction of which was begun in 1805. With basins providing port and access to the two rivers at Gravesend and Strood, the canal passed through a two-mile HighamHigham is a village in the metropolitan borough of Barnsley in South Yorkshire, England.

The line of this old now silted canal can be considered a convenient boundary marking the landward edge of the peninsula.
The section of the canal from Gravesend to the Highham tunnel is now in the hands of the Thames & Medway Canal Association, whose website contains a more complete history, including a map. See http://homepage.ntlworld.com/john.epton/tmca/
Tunnel closure: Engineers and surveyors both governmental and private undertook a consultation and subsequent construction of the recently introduced Medway Towns bypass, which drove a link route directly over the old tunnel, consequently causing geological instability. New housing built along the line of that route has further impacted on its stability. As a result, the tunnel is now closed to trains for the duration of the year 2004.
