Tate Modern was opened on 11 May 2000 by Her Majesty the Queen, on the site of Bankside’s converted power station. To mark Tate Modern’s 21st birthday, we’re celebrating 21 years of Tate Modern’s iconic Turbine Hall at the heart of the gallery, which has hosted some of the world’s most memorable and renowned works of contemporary art. From Louise Bourgeois’ mammoth spider and Carsten Höller’s silver slides to Olafur Eliasson’s glowing sun and Ai Weiwei’s sea of sunflower seeds, the way artists have continually transformed this vast industrial space has revolutionised how we perceive contemporary art.
