Secrets of Underground London

On the surface, London is a buzzing metropolis. But underneath lies secret, hidden worlds, all but forgotten by the millions of people above. These places make up the countless layers of London, and each tells a unique story of the city’s past - successes and failures; victories and tragedies. When the Romans founded settlements along the River Thames during the 1st century AD, they laid down the very first layer of one of the world’s greatest cities. Long buried pieces of the original Roman town still survive to this day – statues, walls, even an entire amphitheatre, where fierce gladiators once fought…and died for glory.
