From 1948 the circuit around the airfield of Goodwood was one of the major venues for British motor racing. However, in 1966 when the owners refused to alter the track to adapt it to the ever higher speeds of contemporary sports cars, the circuit fell into disuse.
In the late 90s Lord March, the owner of the Goodwood estate, decided that the heyday of 50s and 60s racing was worth reviving. Once a year, during the so-called revival weekend, everything is restored to its previous state: Out-of period cars and attire are stricitly prohibited anywhere near the track. All very British indeed.
