Castle Bromwich Assembly was built in the late 1930s for the manufacture of Spitfire aircraft, which continued throughout World War II. Aircraft manufacturing at the plant continued until 1977, when it was sold to Jaguar for car production. The factory remains in use four decades later. Around the same time that the Castle Bromwich Assembly was built, the government built a shadow factory at Solihull, which produced aircraft for the war effort. After the war, the plant was taken over by Rover cars, who relocated from their Lode Lane plant in Coventry. The Land Rover, Britain's first four-wheel drive off-road vehicle, was first produced at the Solihull factory in 1948. The factory expanded and increased in productivity over the subsequent decades to allow for the production of Rover, Land Rover and more recently Jaguar cars.
