Silverstone and Brands Hatch are both holding 50th anniversary-related F1 celebrations this year.
In Northamptonshire, the occasion is the 50th time that the British Grand Prix has been held at the circuit since Maserati pilot Luigi Villoresi won on the then 3.7-mile circuit in 1948, two years before the F1 World Championship was started.
To mark the occasion, visitors to this year's British Grand Prix at Silverstone will be treated to a Heritage Village with displays of key moments in the circuit’s history plus a range of iconic F1 cars.
Meanwhile, in Kent the Masters Historic Festival in 24-25 May will celebrate the 50th anniversary of the first World Championship GP to be held at Brands.
Won by Jim Clark in a Lotus 25, the 1964 event marked a long association of the circuit with F1 and event organisers a promising commemorative parades and displays of F1 cars that were victorious at Brands Hatch.
