The London Borough of Merton is a borough in south-west London, England. The borough was formed under the London Government Act 1963 in 1965 by the merger of the Municipal Borough of Mitcham, the Municipal Borough of Wimbledon and also the Merton and Morden Urban District, all formerly inside Surrey. The borough derives its name from the historic parish of Merton, which was centred on the location now referred to as South Wimbledon. The local authority is Merton London Borough Council.
Merton covers a total area of roughly 14.52 square miles. Merton is served by a wide range of National Rail stations across the borough, as well as the southern tip of the London Underground's Northern line and the District line on the Wimbledon branch. It's the only London Borough which has tube, rail and tram services.
The main industrial centres in Merton are Mitcham, Morden and Wimbledon, of which Wimbledon is the biggest. Other smaller sized centres include Raynes Park, Colliers Wood, South Wimbledon, Wimbledon Park and Pollards Hill. Every year, Wimbledon, one of the four tennis Grand Slam tournaments, is held at the All England Lawn Tennis and Croquet Club in Church Road Wimbledon. The occasion occurs over a fortnight at the end of June and beginning of July and it is the biggest annual sporting event to take place in the UK, attracting over 200000 guests during the Wimbledon fortnight.
