When archaeologists began digging the fields in 2010 they knew it was a site of historical interest, but even they were surprised by the wealth of ancient finds their trowels unveiled.

Back in 1995, a hoard of 400 Roman coins was discovered west of Didcot in Oxfordshire, indicating the land had been lived on for centuries.

As plans progressed for 3,300 new homes, schools and shops on the 180-hectare site, archaeologists were called in to investigate.
