Government representatives from the United States were instrumental in conceiving, developing, and promoting the successful ratification of the World Heritage Convention—formally known as the Convention Concerning the Protection of the World Natural and Cultural Heritage. The US not only developed the concept of incorporating natural and cultural sites in one program, but was also the first state signatory to the Convention. The Office of International Affairs at the National Park Service (within the US Department of Interior) is charged with developing and maintaining a Tentative List (required by the Convention) of US sites. This list recently was updated to include a group of buildings in Chicago known for their contribution to the development of steel-framed skyscrapers.
