A £32m extension to the Tate Gallery in London - the Centenary Development, has now opened with four new galleries and renovations to five original display spaces; the opening heralds a return to traditional chronological picture hanging.

Within the new development a new doorway has been created, the Manton entrance, to reduce overcrowding and give full independent access for disabled visitors. Overall the extension and re-development provides a 35 per cent increase in display space.

Prior to the unveiling of the new galleries, a controversial rehanging of the Tate's collection, displaying works on a thematic basis had been slayed by critics.

The annexe was built with £18m of lottery money and a private donation of £7m from Sir Edwin Manton.

The gallery has remained open throughout the building works and now completes Tate Britain's refurbishment project.
