The are two Tate Galleries, the Tate Modern (Modern Art) at Bankside with the Millenium Bridge and the Tate Britain (Old Masters) further west on the north bank. The must see is the Modern for the Turbine Hall.
Modern buildings interest you?...a trip to the City to see the Lloyds Building and the Swiss Re Tower at 30 St. Mary Axe.
Or opposite the Tower of London to see City Hall.
Or the Royal Academy in Piccadilly to see the Sackler Galleries. The Great Court and reading Room at the British Museum are not shabby either.....
A 1000 years of history.....or like 2000 but hey who's counting....
When are you around?
If you want to see some 'real cars and planes there are a couple of museums on the outskirts of London, the RAF Museum at Hendon...good but not brilliant and Brooklands out near Weybridge, possibly a little far,but but its tops.
1) The first ever purpose built racing circuit in the world....with the original banking in place
2) Great car and plane museum with resotration happening all the time on cars etc and on planes including Concorde...
