It is located on a heath above the River Lea valley, on its south side. Almost all of the village is 90 metres (300 feet) above sea level, with most of the surrounding fields being arable farm land, or cattle and horse grazing.
In 1956 builders laying concrete for the garages in Trinity Road, came across a Belgic grave from about the 40–50 AD period, early Iron Age pottery was discovered and remnants are available to view in the British Museum.
More extensive historical facts can be found here extrapolated from a note written by Esme Nix of Rush Green (an area nestled in the corner of Downfield Road, Hoe Lane, Gallows Hill and the A10, giving the service station and A10 junction its name.)
