West Wickham almost adjoins the picturesque commons of Hayes and Keston. Wickham Court, in which some resemblance to Holland house has been noted, is constructed of warm-red brick, with dressings of Kentish rag-stone. A house is known to have stood here in the reign of Edward IV., and it was this, doubtless, that Sir Henry Heydon rebuilt in the reign of Henry VIII. Anne Boleyn, a relative of the Hevdons, frequently visited the mansion. For three centuries Wickham Court has been the seat of the Leonard family, and it is now the property of Sir John Farnabv Leonard, ho married a daughter of the house and added her surname to his own. Although much altered, it still retains many of its most interesting features and it is beautifully situated, looking out upon a long sweep of park-.
