Sussex Mass & Scratch Dials

Ordnance Survey Bench Mark

These were used to define a known accurate height and position which was (is) used to survey other locations.
The height recorded was at the centre of the horizontal line of the 'Broad Arrow' a government symbol since Tudor times.

On more than one occasion I have been pointed to the 'Mass Dial' only to find it is the Bench Mark which many churches used for as they are stone, solid and unlikely to move or be removed.

Largely superseded by modern GPS instruments, they are being left to the elements. (another part of our heritage)
 

Damaged benchmark at West Itchenor (no dial at this church)
