In the box room are brass and copper objects made on board the Maud. A lot of Amundsen’s letters and photographs were archived here after his disappearance.
Also here are the compass Amundsen used during the sledge journey to the South Pole in 1911 and the theodolite that was used on the Maud expedition. There is also a pelorus, but we do not know on what ship or expedition it was used.
The door leads out to the children’s room.
