The London Borough of Merton, located south-west of central London, celebrates its 50th anniversary in 2015. It was formed as a result of the merger of Mitcham, Morden, Merton and Wimbledon local authorities in 1965, but the area was settled much earlier. Archaeology has shown that Merton was active even in prehistoric times. Celtic warriors were roaming Wimbledon Village long before the shoppers and drinkers of today. You can find the remnants of an Iron Age hill fort to the southwest of Wimbledon Common windmill, and there is evidence of another Celtic fort in the Pollards Hill area of Mitcham.
