To the south of Ambersham, on the Heyshott road, was the Midhurst to Petworth & Pulborough railway, closed in 1966. The bridge, now dismantled, shown in the photo carried the line across this road. The bus coming through the bridge is heading for Heyshott and took skilfull driving to negotiate the arch. On the afternoon of Thursday 31st October 1946 the bus hit the bridge. See enlargement & modern photos.

Ambersham is home to some of the Cowdray Polo greens.   A number of photos of the grounds are in the gallery     The Polo fields served as a Fleet Air Arm airfield during WW2 click here

At the time of the Domesday Survey, there was a long narrow strip, 8 miles from north to south with an average width of ½ mile or less, constituting North and South Ambersham, which was a detached portion of the parish of Steep in Hampshire and formed part of that county until 1844, when the Ambershams were united respectively to Fernhurst and Selham.

Post Office Directory 1867
South Amersham [Ambersham] adjoining Easebourne, is a small hamlet, originally part of the parish of Steep, in Hampshire, but since the passing of the Act of Parliament for settling the boundaries of counties the small slip of land running down from Hampshire into Sussex was severed from the former and added to the latter, and consequently Ambersham became part of Sussex. For purposes ecclesiastical [having no church] it was divided into two divisions, north and south; the former was given to Farnhurst [Fernhurst], and the latter to Easebourne.
