The World Heritage Convention
The UK ratified the Convention in 1984 and, by doing so, joined an international community that has committed to protecting and preserving the world’s natural and cultural heritage.
The Convention initiated a list of World Heritage properties. These properties are sites, places, monuments or buildings of "outstanding universal value" to all humanity – today and in future generations. The World Heritage List includes over 1,000 cultural and natural sites, such as cities, monuments, technological sites, landscapes and geological sites.
The World Heritage List is reviewed annually. There are currently 33 UK World Heritage Sites, 28 of which are cultural sites, and 19 of which are located entirely or partially in England (2023).
Outstanding Universal Value
Sites are inscribed on the World Heritage List because they are considered to demonstrate outstanding universal value (OUV) that makes their permanent protection of the highest importance to the international community.
Outstanding Universal Value means cultural and/or natural significance which is so exceptional as to transcend national boundaries and to be of common importance for present and future generations of all humanity.
To demonstrate OUV, a property must:
The OUV of a site will often differ from its significance. Significance is wide ranging and represents the sum of all the cultural and natural values of a heritage asset. OUV is instead defined for each site in reference to the specific criteria for inscription on the World Heritage List, and consequently will not necessarily encompass all of the values that a heritage asset possesses.
The World Heritage Convention sets out the duties of States Parties in the identification, nomination, protection, conservation, presentation and transmission of the cultural and natural heritage found in their territory.
States Parties to the Convention agree to identify and nominate heritage sites within their territory for inscription on the World Heritage List. It is the responsibility of States Parties to protect and conserve the attributes of OUV of the properties and to provide reports on their conservation to the World Heritage Committee.
The Convention also sets out the duty of States Parties to cooperate with the international community for the protection of world heritage. States Parties agree to help in the identification, protection, conservation and presentation of the cultural and natural heritage situated in other territories as requested.
All States Parties to the Convention meet in General Assembly once every 2 years during the ordinary session of the General Conference of UNESCO. They elect the World Heritage Committee, make policy decisions, and examine the statement of accounts of the World Heritage Fund.
The Department for Culture, Media and Sport (DCMS) represents the UK Government as ‘State Party’ to the Convention and works closely with Historic England, which acts as technical advisor for the implementation of the Convention at cultural sites across the UK. The Joint Nature Conservation Committee (JNCC) also supports DCMS at natural sites. Historic England liaises with the Northern Ireland Environment Agency, Historic Environment Scotland, Cadw and responsible bodies in Overseas Territories in advising on obligations in respect of cultural World Heritage properties in their respective territories.
The World Heritage Committee
The World Heritage Committee is responsible for the implementation of the Convention. It consists of 21 elected States Parties to the World Heritage Convention.
The Committee makes the decisions regarding inscription to the World Heritage List and to the List of World Heritage in Danger. It allocates financial support from the World Heritage Fund and requests action from State Parties when properties are not being managed effectively.
The World Heritage Centre
The World Heritage Committee is supported by a Secretariat appointed by the Director-General of UNESCO. The World Heritage Centre was created in 1992 to carry out this role. The Secretariat assists and collaborates with the States Parties and Advisory Bodies, following the decisions and Strategic Objectives of the Committee and the resolutions of the General Assembly.
