The Kensington Hippodrome was a racecourse built in Notting Hill, London, in 1837, by entrepreneur John Whyte. Whyte leased 140 acres (0.57 km2) of land from James Weller Ladbroke, owner of the Ladbroke Estate, and proceeded to enclose "the slopes of Notting Hill and the meadows west of Westbourne Grove" with a 7-foot (2.1 m) high wooden paling. The race course was not a financial success and it closed in 1842, the land being developed soon afterwards, as Ladbroke began building crescents of houses on Whyte's former race course.
