Images from the Museum of London’s Streetmuseum app give a glimpse into London’s past – in this case, its wartime history. The image above, taken by Police Constable Arthur Cross, official photographer of the City of London Police, and his assistant PC Fred Tibbs, shows bomb damage at Bank Underground Station, following a direct hit on 10th January, 1941. An estimated 111 people who had been sheltering in the Tube died, some of them thrown into the path of an incoming train. The crater that was left outside the Royal Exchange was so large the Royal Engineers had to build a bridge across it.
