Site Event/Activity record ECH4879 - Draft Report of a radar survey in the car park at Chester Castle, 1992

No location map provided. Brief report of a radar survey carried out across 50% of the car park to determine why the car park was sinking in some areas and the verify information taken from other sources regarding services, the moat and subterranean passages. Survey successfully plotted the line of the moat along with evidence for other known structures below the surface. Report concluded that given the level of redevelopment on the site over the centuries there was significant potential for further subsidence and remedial work should be undertaken.
