In London, Tate Modern's new extension, a 10-storey, twisting pyramid-shaped tower, has been unveiled. Switch House, built at a cost of £260m ($367m), contains three new gallery levels, allowing 60% more artworks from the Tate collection to go on show.
Frances Morris, Tate Modern's new director, said the new extension allows the gallery to show more international art and more art by women. "There was a huge deficit in our collecting prior to 2000," she said. "When we opened, 17% of the art on display was by women. Now 50% of the solo rooms are works by women such as Phyllida Barlow and Louise Bourgeois."
The top floor of the new Switch House is an open-air viewing terrace, which will offer visitors spectacular 360-degree views of the London skyline when it opens to the public on Friday 17 June 2016.
