50 free things to do in London
"If you prefer contemporary art to classical works, head to the Tate Modern on the south bank of the River Thames instead, another of London’s top free galleries. The Tate Modern is Britain’s national gallery of international modern art, housing a huge collection of contemporary artworks from 1900 to the present day, with artists including Picasso, DalÍ and Warhol. You can also pop into the public restaurant and bar on floors 9 and 10 of Tate which has some of the most fantastic free views over the Londonskyline."
