If you like architecture, this is a fantastic 3 part series tucked away on BBC4 (episodes 1 and 2 are on iplayer).
It follows the rise of modern architecture and the work of Foster, Rogers, Grimshaw and Farrell. It features iconic buildings such as The Pompidou Centre, Lloyds of London. TV am studio, Sainburys at Camden Lock, the MI6 building, Lords Pavillion..... all designed by these architects.
Tomorrow (final episode) looks like it will feature The Gherkin, The Dome (02), Eden project.
It also explains post-modernism quite well.
