• The Vikings come to the British Museum from today with the first major exhibition in more than 30 years. Vikings: life and legend, the first exhibition to be held in the new Sainsbury Exhibition Gallery, was developed with the National Museum of Denmark and the Staatliche Museen zu Berlin (National Museums in Berlin) and looks at the Viking period from the late 8th century to the early 11th century. Featuring many new archaeological discoveries and objects never seen before in the UK alongside items from the British Museum’s own collection, the exhibition is centred on the surviving timbers of a 37 metre long Viking warship excavated from the banks of the Roskilde fjord in Denmark (pictured). Other items include skeletons recently excavated from a mass grave of executed Vikings in Dorset, the Vale of York Hoard (discovered in 2007) and a stunning hoard of silver from Gnezdovo in Russia. A unique live broadcast event presented by historian Michael Wood taking cinema audiences around the exhibition will be shown in cinemas across the nation on 24th April. Admission charge applies. Runs until 22nd June. For more, see www.britishmuseum.org/whats_on/exhibitions/vikings.aspx. PICTURE: Copyright of the National Museum of Denmark.

Including more than 100 works from the likes of JMW Turner, John Constable, John Martin, Eduardo Paolozzi, Rachel Whiteread and Tacita Dean, Ruin Lust examines the craze for ruins that overtook creative types in the eighteenth century and the subsequent revisiting – and at times mocking – of this fascination by later figures. Works on show include Turner’s Tintern Abbey: The Crossing and Chancel, Looking towards the East Window 1794, Constable’s Sketch for ‘Hadleigh Castle’ c 1828-9, Graham Sutherland’s Devastation series 1940-1 – showing the aftermath of the Blitz, Jon Savage’s images of London in the late 1970s, and Whitehead’s Demolished – B: Clapton Park Estate 1996, showing the demolition of Hackney tower blocks. Runs until 18th May.
