By the time the Kaiser-Friedrich-Museum on Museum Island (today the Bodemuseum) had opened, it was clear that the museum was not large enough to host all of the art and archaeological treasures excavated under German supervision. Excavations were underway in Babylon, Uruk, Assur, Miletus, Priene and Egypt, and objects from these sites could not be properly displayed within the existing German museum system. As early as 1907, Wilhelm von Bode, the director of the Kaiser-Friedrich-Wilhelm-Museum had plans to build a new museum nearby to accommodate ancient architecture, German post-antiquity art, and Middle Eastern and Islamic art.This large three-wing museum had been in planning since 1907; when Alfred Messel died in 1909 his close friend Ludwig Hoffman took charge of construction, which began in 1910. The construction continued during the First World War (1918) and the great inflation of the 1920s. In 1930, the building hosting the four museums opened.
