National Portrait gallery gives a fascinating trawl through British History by the people who shaped it. Starting from medieval kings and arriving at today's actors, musicians and sporting heroes. The emphasis is on the sitter, and not the artist themselves, but that's not to say there isn't any interesting interpretations, many famous modern artists have work displayed here including Lucian Freud, David Hockney and Julian Opie.

The 'Portrait restaurant' has great views over London, although the food prices do pay for the privilege.
