Second World War decontamination centre and rescue unit base at the former Gravesend Council depot on the south side of Canal Road, Gravesend. The decontamination centre building, of unknown design, was under construction by May, 1939. Other existing council buildings - of mainly single storey types - were utilised for the basing of mobile rescue units and first aid parties. The depot appears to have remained in use for civil defence purposes until 1945, and then resumed normal civilian council functions. The buildings of the depot were demolished in phases from the 1980s onwards and nothing remains of the civil defence past of the site which is now (in 2007) being overbuilt with private apartments.
