The Golden Arches may be the most ubiquitous logo in the Olympic Park but the Olympic flag is pretty important too. The iconic rings — designed in 1922 by modern games founder, the marvellously-named Baron Pierre de Coubertin — represent the five inhabited continents of the world.
The rings have been used in various guises in the run-up to the games, nowhere more memorably than the Opening Ceremony, where they were forged in the Industrial Revolution scene (here captured by Julie Ramsden).
The rings hanging on Tower Bridge, meanwhile, apparently glowed last night in celebration of all those gold medals. We're going to miss them when they depart for Rio.
