Between 2012 and 2014, the group of halls dedicated to World War I was completely converted, modernised, and redesigned. To enlarge the initial exhibition area from 1,000 to 1,400 m², the room height was reduced and an intermediate platform was introduced, so that the entire exhibition now spreads over three levels. As a result of these measures, some 2,000 items relating to World War I are now accessible to the public, about twice as many as were on display in the previous exhibition.
