The Conference Building, which can't be seen from the street, lies between the Secretariat and the General Assembly. The three meeting rooms we saw there -- the Trusteeship Council, the Economic and Social Council, and the Security Council -- were like a time capsule of mid-century design.
More specifically, mid-century Scandinavian design -- the three rooms were gifts from, respectively, Denmark, Sweden and Norway. It's obvious they haven't updated much since the buildings were completed in 1952.
Somehow when I've pictured some of the events that have taken place in the Security Council -- Adlai Stevenson confronting the Russian ambassador over missiles in Cuba, Colin Powell's claim that Iraq was hiding weapons of mass destruction -- I never realized that they were taking place in a room with blond wood and baby blue chairs, and lime green seating for the spectators.
