The bench mark is to be found on the north east wall of the farm building. For a wider view of the building Image and for further information on the cut mark http://www.bench-marks.org.uk/bm37240 A bench mark is an Ordnance Survey arrowhead sign found on walls, bridges, churches and specially erected triangulation pillars where the altitude above sea-level has been accurately measured by surveyors. The arrowhead points to a horizontal line above it which marks the exact altitude. With rivets and pivots there is no datum (horizontal line) cut, the pointed-to horizontal surface defining the datum height.
