The New Elizabethans: Norman Foster. James Naughtie considers the significance of the British architect whose prolific output has transformed skylines and landscapes around the world.

Foster's breakthrough was his innovative designs for the Willis Building in Ipswich in 1974, an office complex which now has listed status. He is probably best known for his iconic buildings and structures including Wembley Stadium, the Millau Viaduct in France, and 30 St Mary Axe in London, also known as "the Gherkin".

The New Elizabethans have been chosen by a panel of leading historians, chaired by Lord (Tony) Hall, Chief Executive of London's Royal Opera House. The panellists were Dominic Sandbrook, Bamber Gascoigne, Sally Alexander, Jonathan Agar, Maria Misra and Sir Max Hastings.
