One of London's most popular attractions, this outstanding modern and contemporary art gallery is housed in the creatively revamped Bankside Power Station south of the Millennium Bridge. A spellbinding synthesis of funky modern art and capacious industrial brick design, the eye-catching result is one of London's must-see sights. Tate Modern has also been extraordinarily successful in bringing challenging work to the masses while a stunning extension is under construction, aiming for a 2016 completion date.

The multimedia guides (£3.50) are worthwhile and there are free 45-minute guided tours of the collection's highlights (Level 3 at 11am and midday; Level 5 at 2pm and 3pm). Note the late night opening hours on Friday and Saturday.
