• New galleries dedicated to exploring the history of World War I will open – along with the rest of the refurbished building – at the Imperial War Museum in Lambeth on Saturday. The First World War Galleries span 14 areas displaying everything from shell fragments and lucky charms carried by soldiers to weapons and uniforms, diaries and letters, photographs, art and film. Interactive displays include ‘Life at the Front’ featuring a recreated trench with a Sopwith Camel plane and Mark V tank, and ‘Feeding the Front’ featuring an interactive table of more than four metres long which looks how troops were kept fed. There are also reflective areas in which visitors are encouraged to reflect on some of the most difficult aspects of war. The museum – which features a dramatic new atrium – is also launching the largest exhibition and first major retrospective of British World War I art for almost 100 years. Truth and Memory includes works by some of the UK’s most important artists. Entry to both is free with Truth and Memory running until 8th March. For more, see www.iwm.org.uk.

• London’s memorials to those who died in World War I are the focus of a new exhibition which opened at Wellington Arch near Hyde Park Corner yesterday. The English Heritage exhibition, which has a particular focus on the six memorials cared for by English Heritage but also looks at other memorials, will include designs, statuettes and photographs of the memorials including the Cenotaph in Whitehall. Also featured in We Will Remember Them: London’s Great War Memorials are official documents – including a note of condolence and medals certificates – received by the family of author and broadcaster Jeremy Paxman on the death of his great uncle Private Charles Dickson, who died at Gallipoli in 1915. Runs until 30th November. Admission charge applies. For more see www.english-heritage.org.uk/daysout/properties/wellington-arch/. Meanwhile, coinciding with the opening of the exhibition has been news that five of London’s key war memorials – including the Edith Cavell Memorial in St Martin’s Place and the Royal Artillery Memorial at Hyde Park Corner – have had their heritage listing upgraded.
