The earliest evidence of human activity in Leatherhead comes from the Iron Age. Flints, a probable well and two pits were discovered in 2012 during building work on Garlands Road and the finds suggested that the site was also used in the early Roman period. Traces of Iron Age field systems and settlement activity have been observed at Hawks Hill, Fetcham (about southwest of the town centre) and on Mickleham Downs (about to the south). Also to the south, the Druid's Grove at Norbury Park may have been used for pre-Christian pagan gatherings.
