Member's Comments on North’s Seat...

  • Chris Pearson says...
  • Short steep walk up the rough track at end of Beacon Road to find trig lurking in brambles. In 1787,a triangulation survey from here linked London and Paris, enabling the British and French governments to produce compatible maps and charts that made international sea trade much safer, and therefore more profitable. To do this General William Roy of the British Army set up a 32-feet high scaffold tower about 100 yards north of where North’s Seat is today. On this tower he fixed a unique, highly-sophisticated theodolite with which he could make long-range observations of Sussex and Kent landmarks, and of two places in France. Fairlight Down and Dover Castle were the only English locations that could see both these French sites, and without Fairlight the survey would probably not have taken place. Its success resulted in the setting up in 1791 of the Ordnance Survey.

  • Climbed up to the summit toposcope via Beacon Road and then eventually found the Trigpoint deep in brambles and gorse with a little help from Google Maps. No views as very foggy - 30/12/2016.
