The United Nations Office in Geneva (UNOG), Switzerland, located at the Palais des Nations, is the largest United Nations Office in Europe, providing conference support and facilitating the multi-lateral international diplomacy of the worldwide community. It is located within the 46 hectare Ariana Park.
The United Nations General Assembly approved the establishment of the Strategic Heritage Plan (SHP) which includes the construction of a New Permanent Office Building (NPB) of approximately 22,371 m2, together with the complete renovation of the main Palais des Nations complex of buildings, much of which dates back to the 1930’s. The NPB is to be constructed adjacent to the current building “E”. See Figure 1 attached.
