London Beneath Our Feet

Millions of people walk through the streets of London every day, unaware that another city lies buried beneath their feet—one that's still being found. This first episode of Beyond History uncovers the remarkable story hidden beneath the modern capital. Beginning with a real archaeological discovery made in 2025 beneath Gracechurch Street, we journey back fifty million years to the warm seas that once covered southeast England, follow the rise of Roman Londinium from a small riverside settlement into the capital of Roman Britain, witness its destruction during Boudica's revolt, its centuries of prosperity, its gradual decline, and its disappearance from history. But the story doesn't end there. The evidence continues into the modern world: the Blitz that unexpectedly transformed London's archaeology, the discovery of the Temple of Mithras that captured the nation's imagination, the Bloomberg writing tablets that preserved the earliest known voices of Roman London, the Elizabeth line excavations that uncovered thousands of artefacts beneath the city, and the 2025 excavation beneath the Tower of London that proved there are still extraordinary discoveries waiting underground. This documentary is built on archaeological evidence, historical research, scientific discoveries, and primary historical sources. Rather than asking only what happened, it explores how we know it happened, while remaining honest about the questions historians and archaeologists are still trying to answer. Because history isn't just written in books. Sometimes it's waiting beneath our feet. Beyond History is an evidence-based documentary series exploring the people, places, and discoveries that shaped our world. Every episode begins with a question, follows the evidence wherever it leads, and tells the story as honestly as the evidence allows.
