A trip to London would not be complete without a visit to Tate Modern, Britain's national museum of modern and contemporary art and the world's most visited contemporary art gallery. Housed in the stunning Turbine Hall in a former power plant on the banks of the Thames, this museum is a great place to see the unique artworks of Louise Bourgeois, Yayoi Kusama and Henri Matisse ), Cornelia Parker, Pablo Picasso, Mark Rothko, and many more international and local artists.
