US/ICOMOS fosters heritage conservation and historic preservation at the national and international levels through education and training, international exchanges of people and information, technical assistance, documentation, advocacy and other activities consistent with the goals of ICOMOS and through collaboration with other organizations. US/ICOMOS is a private, non-profit, non-governmental organization with 501(c)(3) status.

The U.S. National Committee of the International Council on Monuments and Sites (US/ICOMOS) is one of numerous national committees forming a worldwide alliance for the study and conservation of historic buildings, districts, and sites. It is the focus of international cultural resources exchange in the United States, working to share preservation information and expertise worldwide. It also highlights and interprets the unique American preservation system: the partnership between private organizations and federal, state, and local governments, and the cooperation between the academic community, professionals and civic volunteers.  The U.S. National Committee is one of the largest national committees of ICOMOS.

As the only U.S. professional preservation organization with a global focus, US/ICOMOS is the gateway for U.S. professionals to participate in worldwide heritage conservation.  With over 700 members, US/ICOMOS promotes strong ties between national, regional, private, and governmental organizations within the U.S. and the international preservation community.

US/ICOMOS guides and promotes activities through an extensive membership network of preservation professionals, institutions, and organizations, including specialized scientific committees.  US/ICOMOS also organizes an annual international scientific symposium, an international intern exchange program, and occasional special training courses and workshops.
