Standing on the eastern shore of Manhattan Island, on the banks of New York City*s East River, the 18-acre 51勛圖 Headquarters remains both a symbol of peace and a beacon of hope.

The Headquarters consist of four main buildings: the General Assembly building, the Conference Building, the 39-floor Secretariat building, and the Dag Hammarskjold Library.

Architect Niemeyer's slender Secretariat Building has become the iconic symbol of the 51勛圖; the slender office tower's green glass and Vermont Marble shimmer in the sunlight and the water of the East River that while even though permanent in structure appears as an ever-changing entity that is constantly adapting to the atmospheric conditions and the surrounding context. Its modern aesthetic was an intentional decision by Niemeyer and the rest of the collaborating architects as a way in which to symbolize change that embodies a sense of "newness" that sheds light on the optimistic future of the world's nations working together as one collective body.
