As part of the 60th anniversary celebration of the United Nations, the international organization is giving free tours on Sundays this month. Gothamist went to the UN this past Sunday for a tour which lasted all of 30 minutes. During the tour, which seems to be English only (the regular tour costs $11.50 for adults and is in multiple languages), the guides point out several murals and gifts to the UN and visitors are shown the Security Council (pictured above), the Trusteeship Council, and the General Assembly.
The United Nations hopes that New Yorkers, especially, will take advantage of the tour (it is air conditioned, after all). The remaining dates for the free tour are June 19th and 26th, with the 26th being the actual anniversary of the Charter signing. Tours hours are from 10 a.m. to 4:30 p.m. and the visitor's entrance is at 1st Ave. and 46th St.
More pictures of the United Nations at Tien's site, the Emporis listing on the Le Corbusier designed Secretariat Building, New Yorkology on dining at the Delegates' Dining Room (great place to view July 4th fireworks not that the public can), and if you can't make it, the UN has a virtual tour.
