Kevin McCloud's Listed Britain

From Coventry Cathedral's medieval ruins that were kept standing, to rescuing a roofless Scottish masterpiece from collapse, Kevin visits places that only survived because losing them was unthinkable. 

Kevin looks at bold, modern places that challenge the idea of what heritage can be, and the places that can be the easiest to dismiss and the hardest to save. He steps inside Liverpool's Metropolitan Cathedral, which is flooded with coloured light from one of Britain's most spectacular stained-glass lanterns, and visits London Zoo's penguin pool, where the aquatic birds are treated to cutting-edge modernism.

Kevin explores places created by people who followed an obsession further than most would dare, and discovers how this singular passion can become something everyone else wants to protect. He climbs the Lovell Telescope at Jodrell Bank, and helps to repair the protected dinosaur sculptures at Crystal Palace Park that captured a Victorian idea of pre-history.
