Clare Balding's at Cardiff Arms Park for this edition of the series that explores how sport made Britain and Britain made sport. Here she looks at the vital role rugby has played in shaping Welsh identity; the stadium was built to be an emblem of national pride, a fortress for Welsh sport in its capital city.

She talks to the legendary Welsh captain and scrum half, Gareth Edwards about Wales' glory days of the sixties and seventies and the impact the introduction of professionalism had on the national side. She also talks to Professor Tony Collins from The International Centre for Sports History and Culture, De Montfort University
