Mystery of the Ice Cream Villa - Yelnow Villa, Colworth, Bedfordshire

Stacks of high quality Roman remains have been found in a rural field near an ice cream research centre, including a huge collection of coins. It points to a high status building, possibly a villa. But it's far from any road, and geophysics doesn't come up with anything definite, apart from a large square ditch. Stewart identifies a potential Roman road, running right past the site. Though they are unable to find a substantial stone building, the outline of an Iron Age round house emerges, showing continuity of occupation over hundreds or thousands of years. Late on day three, evidence of a Roman structure emerges. They are joined by Roman coin specialist Philippa Walton, Ben Robinson from Peterborough City Council and Louise Revell from Southampton University.
