Only UN Member and Observer States, as well as international, inter-governmental and regional organizations, can donate artworks or artefacts to UNOG. The proposed donation should reflect the values and principles of the United Nations. Every donor must first present its donation proposal to the CAC (Cultural Activities Committee) for approval. Under the Strategic Heritage Plan (SHP), the entire Palais des Nations is undergoing a complete renovation starting in 2017, expected to last seven years. During this period, the CAC is not accepting new donation proposals.
