The Silverstone Circuit is a motor racing circuit in Northamptonshire and Buckinghamshire, England, named after the village in the former. It is best known as the home of the British Grand Prix, which it first hosted in 1948 and which has been held on the circuit every year since 1987. The circuit is also home to the BRDC International Trophy, formerly one of the premier non-Championship F1 races in the calendar, today awarded to the winner of a race for historic F1 cars at the annual Silverstone Classic meeting.
