The summer of 2022 saw the celebration of the seventieth anniversary of Queen Elizabeth II's coronation, the first time in British history that a monarch has reached this remarkable milestone. As the event was the first of its kind to be televised, images from the ceremony inside Westminster Abbey are instantly recognisable. Far less familiar are the scenes in the streets outside, where huge crowds assembled to see a procession of state coaches and historic regiments marching past public buildings festooned with patriotic banners and colourful grandstands erected outside many famous landmarks. Using a private collection of more than 200 rare images of London's West End, Protect and Keep looks back to the day that the Queen pledged herself to her country. It provides a unique and precious record of an historic occasion: the day of the Coronation as it was seen by ordinary members of the public.
