Abinger Hammer is a village situated on the A25 between Dorking and Guildford in Surrey, England. Abinger Hammer lies within the parish of Abinger which includes Abinger Common and Sutton Abinger. Other neighbouring villages are Wotton and Gomshall. The River Tillingbourne flows through the village. Brown trout swim in the stream, which is their natural habitat; the occasional larger rainbow trout can be sighted. These may have escaped from the fish farm further downstream towards Gomshall. The Tillingbourne was impounded in the 16th century into a hammer pond, providing water power for Abinger Hammer Mill, also called Abinger Forge, the Hammer forge or Shere forge, which worked Sussex-sourced iron. It has long since been adapted to grow watercress. The hammer mill boomed during the 16th century and the forge was reputed to have even made guns for use against the Spanish Armada. The waters of the Tillingbourne powered the water wheel which drove the massive, 400 kg, trip hammer of the forge. The forge closed in 1787 despite attempts to save or convert it. The clock which overhangs the main road portrays the figure of “Jack the Blacksmith”, who strikes the hour with his hammer. The clock bears the motto “By me you know how fast to go”. The clock was given in memory of the first Lord Farrer of Abinger Hall who died in 1899. The clock represents the iron industry and the role played by the county of Surrey in the industrial past.
