NHER 54371 (Monument record) - World War Two domestic air raid shelters in central Norwich and environs (Ordnance Survey quarter sheet TG11NE)

September 2010. Norfolk NMP.
Small, Anderson or similar types of World War Two air raid shelters are visible as extant structures and earthworks on low-level vertical aerial photographs taken by the RAF in 1945 (S1-S6). Those recorded here fall within the Ordnance Survey 1:10,000 quarter sheet TG11SE, covering the parishes such as Drayton, Taverham, Hellesdon and Costessey. They have been recorded as point data only, for the most part plotted by eye onto the modern Ordnance Survey MasterMap or 1:2500 LandLine map base; their location therefore should be regarded as approximate.
Only those air raid shelters that could be identified with confidence were mapped; any uncertain sites, for example when the low-level 1945 aerial photograph coverage did was not available for the area, were not included within the layer. The NMP mapping of such features in this area should therefore be regarded as both schematic and non-comprehensive; it would in any case only represent those shelters clearly visible and identifiable on the aerial photographs, in itself a proportion of those that presumably once existed.
The vast majority of these shelters were Anderson-type shelters, visible as a earthen-covered semi-sunken oval or sub-rectangular structure. However it must be noted that there was some variation. The most significant area of divergence from this trend was a group of shelters identified in the area of TG 1900 1066 in New Costessey, where a group of sub-surface domestic would appear to have been constructed, accessed by an entrance shaft, similar to those utilised in larger, public shelters. Across the quarter sheet, a total of 108 such shelters have been identified from the photographs. These are largely concentrated in New Costessey. A selection of the aerial photographs consulted are listed within this record (S1-S6); the individual frames on which each shelter is visible are recorded as Object/Attribute Data within the mapping.
