No convincing sign of the World War Two landing strip at this site could confidently be identified on aerial photographs from the 1940s (S4-S5). The only suitable linear features visible were paths within the Park and while it is feasible that these were being used as a temporary landing strip, no evidence for this was identified.
See records NHER 54488-9 for details of medieval to post medieval earthworks within the area of the Park.

Low earthworks and cropmarks associated with the site of Costessy Hall are visible on relatively recent visualised lidar data and aerial photographs (S6-S10). As the lidar survey was flown relatively recently (2021), it is likely that the earthworks still survive. The cropmark foundations of the hall are visible on multiple years of Google Earth and APGB imagery but are seen particularly well on imagery from 2006 (S6-S7) and 2022 (S8-S9) . The cropmarks appear to mostly conform to the extent of the hall as mapped on the Ordnance Survey 1st edition 6" map (S11). Further likely boundaries not recorded on the Ordnance Survey 1st edition 6" map but are probably associated with the hall or perhaps an earlier phase, are visible as cropmarks on S8. Sections of the hall’s foundations are also visible as low earthwork banks (principally located at TG 1636 1128 and TG 1636 1126) on visualised lidar data (S10).
