The UNESCO (United Nations Educational, Scientific and Cultural Organization) has designated 37 World Heritage Sites in eight countries (also called "state parties") commonly referred to as Northern Europe: Iceland, Norway, Sweden, Finland, Denmark, Estonia, Latvia and Lithuania, i.e. a combination of Nordic and Baltic countries. The Danish territory of the Faroe Islands doesn't have any sites. Greenland, lying on the North American continent, is not included in this list despite its political ties with Denmark; it is included in the List of World Heritage Sites in North America. The United Kingdom and Ireland are included in Western Europe even though they are sometimes listed in Northern Europe.
