#UNBlue at the Vienna International Centre

To celebrate the United Nations turning 70, on 24 October the UN70 logo was projected onto the wall of the Vienna International Centre. More than 150 iconic landmarks in over 45 countries around the world, from Australia's Sydney Opera House to the Great Pyramids of Giza in Egypt, and the Empire State Building in New York, were lit up in #UNBlue to mark the 70th anniversary of the UN.
