To visit the UN, one actually leaves New York City and the United States. The 18 UN headquarters is an international zone that belongs to the member nations. The property was originally purchased by John D. Rockefeller and donated for the purpose of providing a home to the world body after World War II. Hour-long tours begin every 30 minutes (in twenty languages!) giving visitors a look at the General Assembly, the Security Council Chamber and the Trustee Council Chamber. Of course, the business of the UN may close particular sections of the tour on any given day, but there is still plenty to see. Along the way you will be able to enjoy various works of art from around the world and a number of displays focusing on themes of world importance.
From time to time tickets are available to the gallery of General Assembly. They are free and offered on a first-come first-served basis. You are also welcome to eat lunch in the Delegates Dining Room. Proper dress and reservations are required. For a quick bite without a dress code, there is a coffee shop on the first floor, where you will also find a number of gift shops.
