A sprawling city with 2,000 years of history, London is a treasure trove of little-visited landmarks and overlooked attractions. Stay eagle-eyed in Trafalgar Square to spot the Lilliputian Police Station—a police lookout no bigger than a phone box dubbed the original CCTV. Or collect sightings of the so-called London Noses, a covert installation project of ceramic noses adorned to buildings across Soho by artist Rick Buckley. Get a sense of wartime Britain at the exceptional Churchill War Rooms; the subterranean map rooms where Churchill and his cabinet met during WWII are unchanged since 1945. A little farther east between Tower Bridge and the Tower of London, St. Dunstan-in-the-East church is a moving reminder of how much the city endured during the blitz. Destroyed in an air raid, it is now a quiet garden in the bustling city.
