United Nations Headquarters in the context of "Central American Integration System"

The United Nations System consists of the United Nations' six principal bodies (the General Assembly, Security Council, Economic and Social Council (ECOSOC), Trusteeship Council, International Court of Justice (ICJ), and the United Nations Secretariat), the specialized agencies and related organizations. The UN System includes subsidiary bodies such as the separately administered funds and programmes, research and training institutes, and other subsidiary entities. Some of these organizations predate the founding of the United Nations in 1945 and were inherited after the dissolution of the League of Nations.

The executive heads of some of the United Nations System organizations, and the World Trade Organization, which is not formally part of the United Nations System, have seats on the United Nations System Chief Executives' Board for Coordination (CEB). This body, chaired by the secretary-general of the United Nations, meets twice a year to co-ordinate the work of the organizations of the United Nations System.

Chapter IV of the United Nations Charter contains the Charter's provisions dealing with the UN General Assembly (UNGA), specifically its composition, functions, powers, and procedures.

The Isle of Portland is a tied island, 6 kilometres (4 mi) long by 2.7 kilometres (1.7 mi) wide, in the English Channel. The southern tip, Portland Bill, lies 8 kilometres (5 mi) south of the resort of Weymouth, forming the southernmost point of the county of Dorset, England. A barrier beach called Chesil Beach joins Portland with mainland England. The A354 road passes down the Portland end of the beach and then over the Fleet Lagoon by bridge to the mainland. The population of Portland is 13,417.

Portland is a central part of the Jurassic Coast, a World Heritage Site on the Dorset and east Devon coast, important for its geology and landforms. Portland stone, a limestone famous for its use in British and world architecture, including St Paul's Cathedral and the United Nations Headquarters, continues to be quarried here.

A permanent representative to the United Nations (sometimes called a "UN ambassador") is the head of a country's diplomatic mission to the United Nations.

Of these, the most high-profile UN permanent representatives are those assigned to headquarters in New York City. However, member states also appoint permanent representatives to the other UN offices in Geneva, Vienna, and Nairobi.

The International Day of Peace, also officially known as World Peace Day, is a United Nations-sanctioned holiday observed annually on 21 September. It is dedicated to world peace, and specifically the absence of war and violence, such as might be occasioned by a temporary ceasefire in a combat zone for humanitarian aid access. The day was first established in 1981 and first observed in September 1982 and is kept by many nations, political groups, military groups, and people.

To inaugurate the day, the United Nations Peace Bell is rung at UN Headquarters (in New York City). The bell is cast from coins donated by people from all continents except Africa, and was a gift from the United Nations Association of Japan, as "a reminder of the human cost of war"; the inscription on its side reads, "Long live absolute world peace".
