Ordnance Survey bench mark with centre bolt on the north-east face of the former Canterbury Workhouse, now an apartment building called Nunnery Fields, off George Roche Road. This bench mark was established in 1850 or 1851 during the First primary levelling of England & Wales, and was levelled with a height of 126.9150 feet [38.6837 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. 263(g). Canterbury Union Workhouse. Bolt in North-east corner; 1.51 ft. above surface (p193). Repointing has obscured the original mark, but the centre bolt is clearly visible four courses above ground level.
