Trafalgar Square is often the venue for political demonstrations and the screening of live sports events, such as football and rugby World Cup matches involving England and cricket's Ashes series.

Nelson's Column, the Fourth Plinth art project, the National Gallery, St Martin-in-the-fields.

Nelson's Column is the standout attraction and the main reason the square is famous. Of course the square also owes its name in part to the monument, which was intended to commemorate victory over Napoleon at the Battle of Trafalgar, in which Nelson himself was mortally wounded.

Should he have triumphed in World War II, one of Adolf Hitler's many schemes was to have Nelson's Column dismantled and reassembled in Berlin.
