BBC News has taken a tour of the Imperial War Museum in London which has just reopened after £40m refurbishment.
The makeover marks the centenary of World War One and includes artefacts such as photographs, letters and tanks.
However, as Robert Hall discovered, it also uses digital technology to bring the events of the past to life.
