Ordnance Survey benchmark with bolt on the north-east face of buttress at St Andrews Church, at south-east corner of the tower. This benchmark was established in 1851 during the First primary levelling of England & Wales, and was levelled with a height of 15.6260 feet (4.7628 metres) above mean sea level (Liverpool datum). It was included as a side level on the London to Dover levelling line. The surveyor's description was "No. 366(e). St. Andrew's New Church, West-street. Bolt in South-west [sic] corner of tower ; 0.58 ft. above surface (p197)." It is now partially hidden owing to resurfacing of the car park.
