For centuries in western culture, opera has been the greatest show on earth. Historian Lucy Worsley explores how history and opera go hand in hand. She visits the great European cities where some of the most famous operas were written, tells the stories of the colourful characters who composed them, and shows how they reflected the turbulent times they were composed in and the lives, hopes and fears of the people who lived in them. Whilst Lucy visits the cities and European opera houses, Antonio Pappano, music director of London’s Royal Opera, helps us understand some of those operas’ greatest musical moments.
