A benchmark is a mark put on a building to indicate a level to aid in map making; the normal approach is to use a triangulation pillar, but hills being in rather short supply in the Fens, other methods had to be used. At one point I thought that this mark on the Town Hall indicated the flood level in 1947, when Corporation Barrier Bank was breached and a large area of farmland was flooded, and there is supposed to be a mark on the building somewhere that indicates this, but I suspect now that it's a surveying mark only.

The well worn Ordnance Survey cut mark is beside one of the doors to the disused windmill on Windmill Hill. For more information visit www.bench-marks.org.uk/bm43499
