This benchmark was established in 1844 during the First primary levelling of England & Wales, and was levelled with a height of 95.455 feet [29.095 metres] above mean sea level (Liverpool datum). It was included on the Manchester to Gloucester levelling line. The surveyor's description was "No.380 Mark on foundation stone of gate pier to Sir Offley Wakeman's demesne, Perdswell [sic]; 1.77 ft. above centre of road" (Public Abstract p.34). The mark is clearly visible on the north-west face of the north-east gatepost at the entrance to Perdiswell Park.
