The Mosaic at the Bottom of the Garden - Cirencester, Gloucestershire

In 300 A.D. Corinium Dobunnorum was England's wealthiest city next to Londinium. Now it's the pleasant Gloucestershire town of Cirencester, and Time Team are visiting the leafy suburban Chester Street, where they hope the back gardens will yield clues about the bustling Roman city and its main highway, Ermine Street. Could a Roman temple have occupied this site - or even rarer, an early Christian church? They need to knock on a few doors to ask about digging up their plots. There is a bottle of champagne for anybody who can find a tessellated pavement. They are joined by Roman architectural historian Tom Blagg, coin expert Richard Reece and mosaic expert David Neal. The Ermine Street Guard offer Tony venison stew, and use a wooden crane to erect a stone column, fashioned by mason Giles MacDonald. In the public presentation, Stewart outlines a picture of the whole city, ably assisted by Victor's drawing. Among many Roman finds are coins, a brooch, a spoon and a bone die.
