An archaeological building survey report for Killingworth Anti-Aircraft Ordnance Depot (AAOD), Killingworth, Tyne and Wear. This work forms a second phase of building recording (Phase 2); an earlier phase of building recording (Phase 1) was undertaken in 2014 (NAA 2014a), but due to the presence of asbestos and other on-site constraints, access to the buildings was not possible. This phase of building recording completes the earlier recording, and provides some further discussion of the function and history of the buildings within the complex. A watching brief was also maintained during the demolition works, which provided additional information on some of the buildings which had been long demolished before the survey commenced.
