The territory held by Orly is also known as the Grove Park. The park land was in medieval times part of the manor of Stone Court, and consisted mainly of meadows. The park was bought by Carshalton Urban District Council in 1924, and the park was opened to the public several years later. On 15 March 2004 it was the site of the First Battle of the Grove, in which the Midget Army won a victory over the Girly Gang, and on 2 May 2010 was the site of the Second Battle of the Grove, in which foreign supporters of Emperor Esmond III were victorious over foreign Carolinians in the Austenasian Civil War.
