This is a fairly large room, measuring 210 m², with a gallery of 48 m². The decor, by the British company White Allom, is very restrained. The light matt background of the walls throws into relief the four great doors - in a rather glossy olive green that gives a bronze effect - each of which is surmounted by a decorative panel depicting the architecture of various countries: a skyscraper for New York, a pagoda for China, etc.

The room has undergone several transformations over the years. In 1970, a podium in three sections was placed under the presiding officers’ table. The number of places for presiding officers was reduced from 16 to 12 and the delegations’ tables were moved half a metre away from the podium. Unfortunately, the installation of interpreters’ booths required the removal of the large world map which originally formed a backdrop to the podium.
