HIDDEN LONDON The Library of Lost Maps At The Guinness Vaults with James Cheshire  on Sunday 12th July 2026 at 4:30 pm In the heart of London’s Bloomsbury, behind a scruffy turquoise door, the world lies folded into drawers. Here are maps that survived wars, regimes, and revolutions — not because they were valued, but because they were forgotten. Some were reused when paper was scarce - a map of Cuba mounted on the reverse of a Second World War map of Berlin, the roads of one ruined city shining faintly through another place entirely, Nazi maps of London intended to be used if Germany come the war, Soviet maps of London marked up with tactical information for espionage. Professor James Cheshire spent three years sifting through the dusty drawers of University College London's map room to research his book The Library of Lost Maps. In this talk he'll share some of his favourite London map finds from the thousands of maps and atlases he discovered on the drawers and shelves of this fascinating but overlooked collection.
