What's Really Buried Under Trafalgar Square?

Beneath one of the world's most visited public squares lies one hundred and twenty-five thousand years of buried history. From Ice Age hippos and cave lions to a headless Roman in a stone coffin, a lost Saxon trading city, medieval royal falconry, seventy thousand buried dead, a wartime bomb that detonated forty feet below the paving stones, and ghost Tube platforms sealed since nineteen ninety-nine, Trafalgar Square is an archaeological excavation site disguised as a tourist attraction. Almost nobody knows what sits beneath their feet.
