The Imperial War Museum has unveiled one of the most astounding historical exhibitions to mark the centenary of World War I, after meticulously creating a sensory assault to immerse the visitor in one of the most horrifying moments in British memory.

After receiving £40m (€51m, $68m) from a number of funders, sponsors, trusts, foundations and individuals, including a grant of £6.5m from the Heritage Lottery Fund and £5m from the Department of Culture, Media and Sport, IWM London managed to transform the entire building into a hub for experiencing the horrors and bitter sweet camaraderie of the First World War.

From personal letters, to tanks, and shells from Big Bertha, IWM London intended to make the First World War galleries as all-encompassing as possible.
