The bench mark is on the milestone in front of St Francis Church. Image and http://www.bench-marks.org.uk/bm33382 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. Milestones are the original roadside heritage features with many dating back hundreds of years and these historic items are under threat from highway developments.
