Firle is a village and civil parish in the Lewes district of East Sussex, England. Firle refers to an old-English/Anglo-Saxon word fierol meaning overgrown with oak. Although the original division of East Firle and West Firle still remains, East Firle is now simply confined to the houses of Heighton Street, which lie to the east of the Firle Park. West Firle is now generally referred to as Firle although West Firle remains its official name.
