UNESCO
UNESCO was created in 1945 in order to respond to the firm belief of nations, forged by two world wars in less than a generation, that political and economic agreements are not enough to build a lasting peace.
Peace must be established on the basis of humanity’s moral and intellectual solidarity.
UNESCO and its mandate for international co-operation can be traced back to the League of Nations resolution on 21st September 1921, to elect a Commission to study the question. The International Committee on Intellectual Cooperation (ICIC) was officially created on 4th January 1922, as a consultative organ composed of individuals elected based on their personal qualifications. The International Institute for Intellectual Cooperation (IIIC) was then created in Paris on 9th August 1925, to act as the executing agency for the ICIC. On 18th December 1925, the International Bureau of Education (IBE) began work as a non-governmental organization in the service of international educational development. However, the work of these predecessor organizations was largely interrupted by the onset of World War II.

Located on the Place de Fontenoy, in Paris, the main building which houses the Headquarters of UNESCO was inaugurated on 3rd November 1958. The Y-shaped design was invented by three architects of different nationalities under the direction of an international committee.
The most important thing for this organism of the United Nations is not to build schools in devastated countries or to publish scientific findings. The primary goal of the Organization is a wider and ambitious one: to construct peace in the mind of men through education, culture, natural and social science and communication.

The Unesco’s logo meaning is that each letter stands as a pillar for the rest of an ancient house that’s because their objective is to preserve culture, science and education.

The World Heritage emblem represents the interdependence of the world’s natural and cultural diversity. It is used to identify properties protected by the World Heritage Convention and inscribed on the official World Heritage List, and represents the universal values for which the Convention stands. While the central square symbolizes the results of human skill and inspiration, the circle celebrates the gifts of nature.
The emblem is round, like the world, a symbol of global protection for the heritage of all humankind.
The most known ambassadors for UNESCO are Ivonne A-Baki, Esther Coopersmith, Vitaly Ignatenko, Keith Chatsauka-Coetzee, Oskar Metsavaht, Ute-Henriette Ohoven, Cristina Owen-Jones but you can check the full list here : http://en.wikipedia.org/wiki/UNESCO_Goodwill_Ambassador
