|Coal Post at Wormley|
Following the Coal Duties Act of 1851 coal posts were erected around London to indicate where tax became due, the tax helping to raise money for many of the bridges across the Thames. At least 44 were in Hertfordshire (but there may have been more). If you want to know more a good place to start is the excellent article "Hertfordshire's Coal Posts" on the Brookmans Park site. It addition to listing all known Hertfordshire posts it has articles, with photographs, on those at Potters Bar, Colney Heath, Hawkshead, Wormley, Northaw and Newgate Street.
