Saudi Arabia's iconic Kingdom Tower and Al-Faisaliah Tower were lit in blue – the official color of the United Nations, as part of a global campaign to commemorate UN Day and the 70th anniversary of the United Nations. The global celebration kicked off in New Zealand and then Australia with the lighting of the Sydney Opera House at dusk, and from there a wave of UN Blue moved across countries and continents as monuments around the world takes part in the international event. World famous landmarks from Australia's Sydney Opera House to the Great Pyramids of Giza in Egypt and the Empire State Building in New York, were lit blue. Other participants included Russia's Hermitage Museum, the ancient city of Petra in Jordan, the Leaning Tower of Pisa in Italy, Edinburgh Castle and Table Mountain in South Africa, Japan's SkyTree Tower, the Alhambra in Spain, among many others. The United Nations Day marks the anniversary of the entry into force in 1945 of the UN Charter. With the ratification of this founding document by the majority of its signatories, including Saudi Arabia, the United Nations officially came into being. "I am grateful our Member States are showing such strong enthusiasm in marking 70 years of UN support for peace, development and human rights," said UN Secretary-General Ban Ki-moon. "By turning the world UN Blue for a day, we can light the way to a better tomorrow."
