Roman remains have been discovered at an archaeological dig at a Cambridge theological college which is planning a £9 million extension.
A major project to update and create state-of-the-art teaching and living space at Ridley Hall meant archaeologists were drafted in to carry out a survey.
After removing the topsoil the experts from Access Cambridge Archaeology discovered the "tantalising possibilities" of a Roman settlement, and even some remains dating back 3,000 years to the Iron Age.
Now the 11-day dig at the hall, founded in 1881, has been opened up to the community with local residents and 20 sixth formers from across the country selected to volunteer at the site and have a hand in recording its history.
Dr Carenza Lewis, director of Access Cambridge Archaeology, told the News: "There are tantalising possibilities here.
"We have found signs of a Roman settlement and there may also be some Iron Age remains which will be excavated and recorded.
