The club rented Green Street House and grounds in the Municipal Borough of East Ham from the Roman Catholic Church from around 1912. Green Street House was known locally as Boleyn Castle because of its imposing nature and an association with Anne Boleyn, who had either stayed at, or as some believe, owned the house, the ground is said to be haunted by one of her maids who died in childbirth. Hence renting the grounds of "Boleyn Castle" the Boleyn Ground came into being. Today the ground is far more commonly known as Upton Park, after the Upton Park, London area in which it is located.
