Earl's Court is a district of Kensington in the Royal Borough of Kensington and Chelsea in West London, bordering the rail tracks of the West London line and District line that separate it from the ancient borough of Fulham to the west, the sub-districts of South Kensington to the east, Chelsea to the south and Kensington to the northeast. It lent its name to the now defunct pleasure grounds opened in 1887 followed by the pre–World War II Earls Court Exhibition Centre, as one of the country's largest indoor arenas and a popular concert venue, until its closure in 2014.
