[1] Flint implements and flakes are not uncommon in Warlingham and Chelsham: evidence of a neolithic population frequenting the area.

The overlordship remained in the Clare family until the death of Gilbert de Clare Earl of Gloucester without issue in 1314; one third of the estates taken by Hugh le Despenser (from one of Gilbert's three sisters) included this manor, passing down the family Beauchamps and Nevills to King Richard III through his wife.

[2] In 1455 a sale took place to Sir Thomas Cook, a draper and Alderman of the City of London, who mortgaged it to Robert Harding, goldsmith, could not pay most and who then became lord of this manor; his son who inherited William Harding, merchant of London, died in 1549.

[n 1] Four younger sons shared a £20 per year annuity each as an elder Uvedale brother inherited, one of these was Richard Uvedale, one of these younger sons, described as of Chilling, Hampshire and Chelsham Court, Surrey was implicated in the Dudley conspiracy in Mary I of England's reign.

They ran this small estate but the priory was suppressed by Cardinal Thomas Wolsey under a bull of Pope Clement VII dated September 1524 for the endowment of his foundation of Cardinal College, Oxford and this manor was granted to him by Henry VIII in January 1526.

On his death in 1556 it passed to his wife Katherine and their son William, Beatrice widow of the latter holding it in 1604.

Later the estate was sold in parcels to various people, about 120 acres being now part of Chelsham Court Farm.

It cost £200,000 to lay out grounds and erect the buildings, including the iconic central tower which is the only edifice that still stands.

In 1911 gravel diggings[11] were present as a form of small industry within the Worms Heath and Elmes & Son had plant nurseries at Langhurst.

[12] Chelsham lies high and commands views for a long distance, including over London,[13] from the centre of which it is 15.3 miles (24.6 km) south by south-east.

The highest point of the North Downs Area of Outstanding Natural Beauty is a slight, gentle rise, about three miles south of the village along Croydon Road at Botley Hill.

It was built to serve the farms in Chelsham, and still sits in farmland in the centre of the roads and bridle ways of the parish.
