This spectacular renovation of a mid-20th-century power station is one of the most-visited museums of modern art in the world. Its great permanent collection, which starts in 1900 and ranges from Modern masters like Matisse to the most cutting-edge contemporary artists, is arranged thematically—Landscape, Still Life, and the Nude. Its blockbuster temporary exhibitions showcase the work of individual artists like Gaugin, Roy Lichtenstein, and Gerhard Richter.
The vast Turbine Hall is a dramatic entrance point used to showcase big, audacious installations that tend to generate a lot of publicity. Past highlights include Olafur Eliasson's massive glowing sun and Carsten Holler's huge metal slides.
The museum is in the process of rearranging its galleries prior to the opening of an ambitious new extension in 2016, so check the website ahead of time. Not to be missed is the new collection of Rothko murals, originally created for the Seagram building
in New York, and displays devoted to Cy Twombley and the video pioneer Nam June Paik (both on Level 4).
Head to the Restaurant on Level 6 or the Espresso Bar on Level 3 for stunning vistas of the Thames. The view of St. Paul's from the Espresso Bar's balcony is one of the best in London.
Join a free, 45-minute guided tours. Each covers a different gallery: Poetry and Dream at 11, Structure and Clarity at noon, and Energy and Process at 2. There's also a daily modern art talk at 3.
Levels 2 and 3 include temporary exhibitions, for which there's a charge. The main collection is free. Look for the ever-changing video installations scattered throughout the building.
