Outstanding universal value

Outstanding universal value is the significance that makes a cultural or natural property so exceptional that it merits recognition and protection as World Heritage under the 1972 UNESCO convention.

World Heritage Convention: The 1972 international treaty establishing the system for identifying and protecting cultural and natural World Heritage. It establishes the obligation to identify properties with outstanding universal value.
Statement of Outstanding Universal Value: The official summary of a World Heritage property's significance, criteria, integrity, authenticity, and protection requirements. It records how a property's value is justified and what must be sustained.
National heritage: Cultural and natural places a country recognizes as significant to its history, identity, or environment. A place can matter nationally without meeting the convention's standard of universal significance.
World Heritage conservation: The protection and management of properties inscribed on the World Heritage List. Conservation must preserve the attributes that convey a property's recognized value.
World Heritage Site selection criteria: Ten UNESCO criteria used to assess whether cultural or natural properties have outstanding universal value. At least one criterion must be met for a property to qualify.
Tentative List: A country's inventory of properties it may nominate for World Heritage inscription in the future. A property must generally appear on its country's Tentative List before nomination.
World Heritage List: The UNESCO list of cultural and natural properties recognized as having outstanding universal value. Inscription records international recognition, while the value itself is the basis for inscription.
Impact assessment (World Heritage): The evaluation of how proposed changes may affect a World Heritage property's significance and attributes. Assessment helps prevent development from damaging the features supporting its value.
Integrity (World Heritage): The wholeness and intactness of a World Heritage property and the elements needed to express its value. Integrity tests whether a property's significant features remain sufficiently complete and undamaged.
World Heritage nomination: The formal proposal a State Party submits for a property to be inscribed on the World Heritage List. The nomination must demonstrate the property's value against the selection criteria.
