A small square room measuring 56 m², this was once the office of the President of the Council of the League of Nations. Not only was it the office of the President of the Council, however - it also enabled Council members to hold “secret meetings”.

The decor was designed by White Allom of London, and the walls are covered with the thinnest veneer of maple with silver highlights, commissioned and paid for by the League of Nations. The furnishings, a gift from the Government of Sweden, and manufactured by the Nordiska Kompaniet, are made of a type of oak immersed over a long period in the waters of a large lake in the north of Sweden, acquiring in the process the most unusual, almost metallic green hue and a unique sheen.

There are three main spatial divisions in the room: an area containing a writing desk formerly used by the President of the Council, a small reception area for visitors and a large oval conference table extending the full length of the room. The table seats 18 and has a polished oak top with marquetry work in three varieties of wood depicting a map of the world and showing the oceans, the continents and the principal mountain ranges. The desk top is covered in red leather, as are the 22 chairs and armchairs. The reception area comprises an occasional table and two armchairs. The table has stainless steel legs and a solid glass top engraved with scenes from Swedish country life - a hunter standing, gun to shoulder, two woodsmen sawing down a tree and a farmer sowing corn. The floor is covered with a large Persian carpet.

Room II was first used at the 94th session of the Council, from 2 to 10 October 1936.
