|Croydon Airport (ICAO: EGCR) was an airport in South London which straddled the boundary between what are now the London boroughs of Croydon and Sutton. Croydon was the first airport in the world to introduce air traffic control, in 1921. It was the main airport for London before it was replaced by Northolt Aerodrome, London Heathrow Airport and London Gatwick Airport. Both the terminal building and entrance lodge are Grade II listed buildings.|
It originated as two adjacent World War I airfields - Beddington Aerodrome, one of a number of small airfields around London, which had been created for protection against the Zeppelin raids in about May 1915, and Waddon Aerodrome of 1918, a test-flight aerodrome adjoining National Aircraft Factory No 1. Croydon Airport's Aerodrome Hotel is part of Croydon Vision 2020 regeneration plan.
