Named after a major victory in the Napoleonic Wars, Trafalgar Square is the largest paved, public square in the city. At its center is Nelson's Column, a 52 meter (170 foot) statue of the Admiral himself.
The most significant attraction on the square is The National Gallery, a public art gallery that is small in size as compared to other European national galleries, but incredible in the scope of artwork it presents. Exceptional works include Van Gogh's Sunflowers and originals by Cezanne, Da Vinci, Monet, and many more.
Note:Entrance to the museum is free, although there are ticket fees for special exhibits.
