Welcome to the bench mark database.
The database contains records of Ordnance Survey bench marks, with particular focus on the numbered flush brackets which appear on walls and buildings across Britain. In addition, fundamental bench marks, projecting brackets, tidal observatories, and other bench marks are also included, to help give a more complete picture of the levelling lines.
