Nick Knowles follows the skilled and passionate artisans trying to save Exeter Cathedral from succumbing to the Great British weather! It was no accident that the Cathedral was at the top of Hitler’s list when he decided to bomb Britain’s best heritage buildings. Today its enemy is the weather and the task of restoring its incredible stonework, including grotesques, pinnacles and stunning West Screen statues, is an endless one. Another huge challenge is to preserve some of the country’s oldest medieval stained-glass dating back 700 years. And Nick joins the team uncovering original fourteenth century paintings hidden for decades.
