Chalkhill orchard is on public open space in front of Chalkhill estate in Wembley Park. It dates from the 1960s and includes veteran apples, pears, plums and a walnut tree. Orchard History Chalkhill estate was developed as a Metroland estate in the 1920s (Metropolitan Railway's property company developed housing estates on land that it had bought beside its railway lines, promoting the benefits of living in the countryside of Metroland) and enlarged between 1966 and 1970. The orchard was probably planted as part of the landscaping of the estate.
