With an area of more than a million square miles, Queen Maud Land is the section of Antarctica claimed by Norway, and annexed in 1939. Queen Maud Land has no permanent inhabitants, but up to 40 scientists inhabit the 12 research stations there. Please note that the Antarctic Treaty System, ratified in 1959, ensures free scientific access to the continent. Therefore, while Queen Maud Land is officially Norwegian territory, Norway is barred from using the land for military or economic purposes. Scientists from any country are allowed to do research there.
