classified as having sovereignty but does not claim any territory in Rome or anywhere else, hence leading to dispute over its actual sovereign status. Rome is the seat of the so-called "Polo Romano" made up by three main international agencies of the United Nations: the Food and Agriculture Organization (FAO), the World Food Programme (WFP) and the International Fund for Agricultural Development (IFAD). Rome has traditionally been involved in the process of European political integration. The Treaties of the EU are located in Palazzo della Farnesina, the seat of the Ministry of Foreign Affairs, because the Italian government is the depositary of the treaties. In 1957 the city hosted the signing of the Treaty of Rome, which established the European Economic Community (predecessor to the European Union), and also played host to the official signing of the proposed European Constitution in July 2004. Rome is the seat of the European Olympic Committee and of the NATO Defense College. The city is the place where the Statute of the International Criminal Court and the European Convention on Human Rights were formulated. The city hosts also other important international entities such as the IDLO (International Development Law Organisation), the ICCROM (International Centre for the Study of the Preservation and Restoration of Cultural Property) and the UNIDROIT (International Institute for the Unification of Private Law).
