The team open the doors to the Museum's own disused site, Clapham South deep-level shelter, part of our popular Hidden London tours programme. We take you behind the scenes of the tour to reveal fascinating places too difficult to normally visit using 3D scans, Chris explains his role as custodian of the site and we meet Martin, the Conservation Engineer who has restored many of the original systems from the Second World War.
