In 1904 the Gemäldegalerie moved to the newly built Kaiser Friedrich Museum, now the Bode Museum, where the collection continued to expand. The museum was badly damaged during World War II, but most of the collection survived the war in shelters across Germany. At the end of the war, however, 400 works that were regarded as too large to take to the remoter hiding places were destroyed in a fire in a Flak tower that served as a bomb shelter. Many important altarpieces and other large works were lost, and the collection remains short of very large works compared to the other major European collections. Furthermore, several hundred paintings were looted by Russian or American soldiers or confiscated by the Red Army and never returned, although in June 2006 a small painting by Alessandro Allori, missing since 1944, was returned by the British journalist Charles Wheeler, who had picked it up at the end of the war in Berlin. The surviving collection was divided between East Berlin (mostly at the Bode Museum on Museumsinsel) and West Berlin in Berlin-Dahlem, where from the 1950s they were housed in a building originally used for the Asiatic collections, built in 1923, with post-war additions.
