The term UNESCO uses for heritage significance considered exceptional beyond national boundaries.
Outstanding Universal Value is a formal concept within the World Heritage system. It is not a star rating, a popularity score or a claim that a visitor will prefer one place to another. A property's stated value explains the attributes for which it has been inscribed.
Read that statement before deciding what matters in a visit. It may emphasise an ecological process, an exchange of ideas, a settlement pattern or a testimony to history rather than the feature most often photographed. The inscribed boundary and its components also matter.
The project's five collections are independent editorial selections. Inclusion here does not create a UNESCO designation, and a lower project number is not a UNESCO ranking. The official property link is the place to check the precise designation and its rationale.

Does the official reason for recognition match the feature you first noticed in photographs?
