National Portrait gallery gives a fascinating trawl through British History by the people who shaped it. Starting from medieval kings and arriving at todays actors, musicians and sporting heroes. The emphasis is on the sitter, and not the artist themselves, but thats not to say there isnt 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. Entry: Free (except certain exhibitions) Nearest tubes: Leicester Square/Charing Cross Other galleries within walking distance: Photographers Gallery, ICA, National Gallery.
