CLEAN : Inside the UN headquarters, a treasure trove of art

The video discusses the art collection at the UN, initially a mystery due to anonymous donations, later revealed to be from Nelson Rockefeller. The UN, not a museum, houses nearly 400 art pieces, donated by various countries. These donations must be managed carefully to maintain diplomatic balance. The UN accepts art gifts but not their upkeep, which remains the donor's responsibility. A stained glass window, a significant piece, is highlighted. The video also touches on the cultural impact of art, particularly a sculpture that inspired a poem by East German opposition figure Wolf Biermann.
