Watch Elodie Harper's report below.
It was a case of old meets new in Cambridgeshire, an archeological dig is taking place at the site where the new town of Northstowe will be built.
The main focus is a large Roman settlement. People were born and died here, and today traces of their lives were on display to the public.
Northstowe will house up to 24 thousand people, this settlement would have numbered in the hundreds, but it was still a popular place to live after the Romans left. A Saxon settlement has also been found.
The square mounds of brick are from the much more recent past - they belong to the old RAF barracks.
Today the public were given tours round the site. There were activities for children too.
