Hidden history. This small arrow cut into the stone is a damaged Ordnance Survey benchmark. The horizontal datum line above it has been lost to weathering. Churches were used because they were solid, permanent landmarks. This point fixed the church at 18.127m above sea level. Easy to miss — but part of Britain’s mapping history. | St Oswald's Church, Methley
