The Royal Collection is one of the most wide-ranging collections of art and artefacts in the world and provides an intriguing insight into the minds of the monarchs who assembled it. During the series, Will Gompertz encounters dozens of these unique objects - some priceless, others no more than souvenirs - each shedding light on our relationship with the monarchy and giving a glimpse into the essential ingredients of a successful sovereign. In this programmes, Will explores the relationship the institution of the monarchy has had with that potentially corrosive agent - change. He finds that the most successful monarchs have understood and harnessed innovation - Henry VIII took an interest in wood so the Navy boats would be the best on the ocean, Charles II established the Royal Observatory so astronomers could find out more about the skies and better inform navigation. Queen Victoria asked Marconi to demonstrate a radio station at Osborne House and she took part in the first trans-Atlantic cable ever sent. With the help of objects and curators from the Royal Collection, together with leading historians, Will studies objects that not only demonstrate the patronage of the arts and sciences but also illuminate the more personal expressions of learning and monarchical intellectual engagement.
