A country must first list its significant cultural and natural sites; the result is called the Tentative List. A country may not nominate sites that have not been first included on the Tentative List. Next, it can place sites selected from that list into a Nomination File.
The Nomination File is evaluated by the
International Council on Monuments and Sites and the
World Conservation Union. These bodies then make their recommendations to the World Heritage Committee. The Committee meets once per year to determine whether or not to inscribe each nominated property on the World Heritage List and sometimes defers or refers the decision to request more information from the country which nominated the site. There are ten selection criteria – a site must meet at least one of them to be included on the list.
