The historic county boundary between Surrey and Sussex ran to the south of Gatwick Airport. Boundaries were reformed in 1974 with the county boundary between Surrey and West Sussex, delineated by the Sussex Border Path, running along the northern perimeter of the airport, and the southern extent of Charlwood.
