A location must be of universal importance and satisfy one of the selection criteria established by UNESCO in order to be designated a World Heritage Site. A country's State Party, or in the case of the UK, the Government, creates a preliminary list of sites that should be taken into consideration for inscription. They are then assessed by either the IUCN (World Conservation Union) for natural sites or ICOMOS (International Council of Monuments and Sites) for cultural sites. The World Heritage Committee then reviews the sites before making a judgment. Documents proving the property's "Outstanding Universal Value" and a management plan proving that safeguards are in place for its continued protection and preservation must be produced as part of the nomination process.

What does it mean for a place to be a heritage site?

Among the most valuable and precious possessions of not only each nation, but also of humanity as a whole, are the cultural heritage and the natural heritage. Any of these most valued things that are lost due to destruction or disappearance impoverishes the cultural heritage of all peoples in the world. Some of that heritage can be seen as having remarkable universal significance due to their exceptional qualities, making them deserving of special preservation from the threats that are posing a growing threat to them. The aim is to determine the locations deserving of the designation of World Heritage Sites and subsequently to assure their preservation and protection.

What requirements must be met for a site to become a world heritage site?

A site which is nominated for inclusion in the World Heritage List will be considered to be of outstanding universal value for the purpose of the Convention when the Committee finds it meets one or more of the criteria, the Operational Guidelines for the Implementation of the World Heritage Convention states. The following standards must be met for cultural properties to be included to the World Heritage List:

-represent a work of art created by human creativity.

-display a significant exchange of human values throughout a period of time or within a particular cultural region of the world on advancements in monumental art, urban planning, or landscape design.

-bear a singular or at least extraordinary testimony to an existing or extinct civilization, cultural legacy, or both

-be a superb example of a particular building form, architectural ensemble, technical advancement, or landscape that exemplifies a key stage in human history.

-set a high standard for traditional human habitation or land usage that exemplifies a culture, particularly when that culture is at risk from irreversible change.

-have a direct or indirect connection to historical occurrences, living customs, concepts, or beliefs, as well as to exceptional universally significant works of art and literature.

-pass the authenticity test for design, material, workmanship, or setting, as well as for cultural landscapes' unique features.

-have sufficient legal, contractual, traditional, and/or management measures in place to guarantee the preservation of the nominated cultural assets or cultural landscapes. Therefore, the presence of proper management and/or planning control mechanisms as well as of protective legislation at the national, provincial, or local levels, as well as of a well-established contractual or traditional protection, is crucial, as is evident in the following.

-be exceptional illustrations of key eras in the history of the planet, such as the record of life, significant ongoing geological processes in the formation of land shapes, or noteworthy geomorphic or physiographic features.

-represent important ongoing ecological and biological processes in the growth and development of terrestrial, freshwater, coastal, and marine ecosystems and communities of plants and animals.

-have extraordinary natural phenomena or regions of exceptional aesthetic value and natural beauty

-contain the most important and significant natural habitats for in-situ conservation of biological diversity, including those containing threatened species of outstanding universal value from the point of view of science or conservation

-contain the most crucial and vital natural habitats for the in-situ preservation of biological diversity, particularly those containing threatened species of high global importance from the standpoints of science or conservation.
