Cragside was the home of William Armstrong, a Victorian industrialist, scientist and philanthropist who came to be known as the ‘Modern Magician’. Join Alan as he explores the world’s first ‘eco home’ – lit by hydroelectric power and brimming with Armstrong’s ingenious inventions that intrigued even royalty. In Cragside’s Pinetum, Miriam O’Reilly tests her head for heights as she scales one of its towering trees, while Angela Rippon heads to William Morris’s home near London to learn about another of Armstrong’s passions: the Arts and Crafts movement.
