When it emerged from the earth it was dull, corroded and battered, the centuries it had spent lying beneath a Somerset field having taken their toll.

Now restored and gleaming, the Cheddar brooch, a rare early medieval piece regarded as one of the most important finds of its kind, is going on display at a museum close to where it was found by a metal detectorist.
