This year's Reith lecturer is Richard Rogers, one of the most influential British architects of our time. He has established himself and his practice at the forefront of today's architecture industry through such high-profile projects as the Pompidou Centre, the headquarters for Lloyds of London, the European Court of Human Rights in Strasbourg and the Millennium Dome in London. His series of lectures is entitled 'Sustainable City' and each lecture focuses on architecture's social role and the sustainable urban development of towns and cities through social and environmental responsibility.

In his third Reith lecture, Richard Rogers examines the ways in which buildings can enhance the public sphere and argues that our sometimes over-zealous preservation of buildings allows our architectural heritage to choke our future. Only by tailoring buildings to the changing needs of people and the environment, he says, can we sustain the public life of our cities.
