British Museum (entry is a donation): contains the Rosetta stone, Elgin marbles, Sutton Hoo treasures, and many other rare artifacts that the Brits stole from other lands mostly in the 19th century.

The Tate galleries: fee to get in but contains some astonishing original work of famous artists such as William Blake and many contemporary artists

The London Dungeon: fee to get in.  Situated at the foot of the London Eye, it takes you on a walking tour of the horrors, torture methods, and cataclysmic moments in British history.

The Museum of London: fee to get in.  A surprisingly original, fascinating, and moving exhibition that traces the history of London.

The Victoria and Albert Museum (the V&A): fee to get in.  Broad and fascinating cultural artifacts covering a range of British history and culture.  There are mss here as well.  Like the British Museum and British Library, the V&A houses rare artifacts and provides exhibitions that put a spin on moments in British imperial history esp.

The National Gallery and Trafalgar Square: free.  We will probably end up here as a group.  Definitely worth a visit if we don’t.
