2000 years ago, London didn’t exist. It was created by the Romans in the first century AD. They settled just over there in what we now call the city. It started as a simple bridge over a river, but within a hundred years had become a bustling city with a population of 30,000. But it was a long way from Rome, and Londinium has always been considered a bit of a frontier town, an unsoffisticated outpost perched precariously on the very edge of the Roman empire, until now. Over the last nine months, archaeologists from the Museum of London have been working on a site right in the heart of the city, and what they’ve discovered, suggests that Londinium was in fact one of the most soffisticated and advanced cities in the whole Roman empire.
