When World War II was imminent in 1938, the museum was closed. The artworks were mostly safely stored away when the gallery building itself was severely damaged in the bombing of Dresden on 13 February 1945. At the end of the war in 1945, most of the paintings were confiscated by the Red Army and transported to Moscow and Kiev. On their return to Dresden in 1955, part of the collection was displayed on the ground floor of the still partly destroyed Semper Gallery. The Old Masters Gallery re-opened in 1960 after the reconstruction of the gallery building was completed. While the most important paintings survived this period, the losses were significant. Records from 1963 state that 206 paintings had been destroyed and 507 were missing.[1] Of these, some 450 are still missing today.[1]
