Our city archaeologist makes a welcome return to explain how people crossed the Forth before there was a bridge at Stirling. According to tradition, the Fords of Frew are the only crossing point on the river west of the city. They were refortified by King Kenneth II; Bonnie Prince Charlie and Montrose both crossed here. Murray Cook guides us through the facts and fables of Scotland’s forgotten frontier, which divided Picts from Northumbrians.
