Art gallery Tate Britain's £32.3m centenary development opens to the public today.
The project, the most significant change to the gallery since it opened in 1897, gives it a modern entrance, with 10 new and five refurbished exhibition spaces built into the neo-classical structure.
Architect John Miller said the key was "light and space", adding that he prefers "galleries which do not try to upstage the art."
The increased space will allow important works to be brought out of storage. Artists such as Bacon, Gilbert and George, Gainsborough, Blake and Turner will be given more space.
Tate Director, Sir Nicholas Serota, said that the new building is "only the beginning" of his plans for Tate Britain.
The opening show is 'Exposed: The Victorian Nude', which draws together works by Rossetti, Alma-Tadema, Sargent and many others.
