This Old Airfield is said to be one of the best-preserved World War II airfields in the country. There are still four runways in good order and a number of airfield buildings on site, including a unique hangar, the Northlight Hangar.
The place first operated as a Royal Navy and then an RAF airfield toward the end of World War I. It then reopened in World War II as a naval air station primarily operating Swordfish torpedo biplanes. During the cold war, the station later became the site of the Joint Services School for Linguists.
