Egham Hythe, Pooley Green and Thorpe Lea are adjacent settlements in the Borough of Runnymede in Surrey, England, approximately 18 miles (29 km) west of central London.

In the centuries around the time of the Norman Conquest the tything of the Hythe, which belonged to Chertsey Abbey, supported only shepherd's tenements and lowly agriculture dwellings due to flooding quite often by the river Thames.

The last long lessee of the manor, still somewhat intact, was Priscilla Edgell who married Richard Wyatt in 1766, their surnames giving rise to the current names of streets.

[4] Thomas de Oxenford to protect many fields, even Chertsey from common winter deluge and summer flash flooding at his own expense constructed the great Egham Causeway, leading from the town of Egham to the bridge of Staines, in the time of Henry III to be used as a highway and as a dyke (embankment), which prevented the inundation of "all the surrounding country" by the River Thames as caused regularly following prolonged heavy rainfall.

[3] By 1385 the Sheriff of Surrey was irked by the causeway's condition and ordered by public proclamation: ...that all persons, ecclesiastical as well as secular, shall each, according to the extent of his holding, cause the same to be repaired with all haste.

Using the large passing trade of Staines Bridge various ordinary people in the 15th century were bound to keep up the causeway including Thomas Stanes, John Edmed, William Mulso in return for being given the right to levy tolls (grants of pontage).

[5][6] One of the two significant commons of Egham here known as Hythefield, was stated to be in Stevenson's 1809 survey[7] more highly rent-able than most such common of Surrey[3] were it to be made private, was enclosed on 12 June 1817 – to this day two large publicly administered allotments provide fertile soil in the Pooley Green locality for tomato and vegetable growers who wish to hire these, subject to a waiting list.
