This benchmark was established between 1850 and 1856 during the First primary levelling of England & Wales, and was levelled with a height of 356.2100 feet [108.5728 metres] above mean sea level (Liverpool datum). It was included as a side level on the Basingstoke to Coventry levelling line. The surveyor's description was "No. 132(b). Wootton Church. Bolt on South side of tower; 3.22 ft. above surface" (Public Abstract p. 238).
