Folkestone Racecourse was a thoroughbred horse racing venue in southeast England, until it closed in 2012. It is located in Westenhanger, by junction 11 of the M20 motorway and about 6 miles (9.7 km) west of Folkestone. The course remains closed and all running rail and steeplechase fences have been removed. In May 2016 it was revealed that the land covered by the racecourse forms part of a plan to develop and build housing. It is now unkempt and in a state of disrepair.

Westenhanger Castle is a fortified manor house once owned by royalty, located next to Westenhanger railway station and the grandstand of Folkestone Racecourse in Kent. The castle has endured a period of steady decline to near ruination in recent years, but the current owners have engaged a programme of consolidation, conservation and restoration to the castle and adjoining buildings. It is now being used as a conference and wedding venue.
