Ian Marchant is time-travelling through Herefordshire’s Golden Valley in springtime. He learns about "the wine of the west" in cider-maker Denis Gwatkin’s orchards, discovers Herefordshire’s lost castle at Snodhill, and visits an Elizabethan watermeadow system in Turnastone. Ian finds out why modern-day pilgrims are walking through the Golden Valley. High above it, he visits ancient Arthur’s Stone which captured the imagination of CS Lewis. Win Scutt from English Heritage tells Ian of exciting archaeological discoveries about the dolmen, built by Neolithic cattle herders.
