It's been a terrible week in London, and in other British cities, too. Lives have been lost, homes destroyed, businesses ransacked and historic buildings burned to the ground.
London will pick itself up, though, as it always does. Already, funds have been set up to help traders whose shops were looted and citizens, mobilised using social networks, have come together to clean up their local areas.
As the Blitz wore on, rosebay willowherb wreathed the mourning city in purple, and it remains today the county flower of London.
