World Heritage

World Heritage Convention

The World Heritage Convention was adopted by UNESCO in 1972, and ratified by the UK in 1984. It describes the kind of natural or cultural sites of ‘outstanding universal value’ (OUV) that can be considered for inscription on the World Heritage List.

UNESCO World Heritage Committee

The UNESCO World Heritage Committee meets once a year. It is responsible for implementing the World Heritage Convention. Its role is to:

decide which sites from the Tentative List to inscribe onto the World Heritage List
look at State of Conservation reports
ask States Parties to take action if sites are not being properly managed
decide which sites to put on the List of World Heritage in Danger

The records of the World Heritage Committee sessions can be accessed here.

The Advisory Bodies – ICOMOS, IUCN and ICCROM

There are three advisory bodies named in the World Heritage Convention, who advise the World Heritage Committee. These are ICOMOS (International Council on Monuments and Sites), IUCN (International Union for the Conservation of Nature) and ICCROM (International Centre for the Study of the Preservation and Restoration of Cultural Property). ICOMOS advises on cultural sites, IUCN on natural sites and ICCROM on education and training.

UK World Heritage Sites

There are currently 35 World Heritage Sites in the UK. Each site has a World Heritage Site Co-ordinating Committee (or Steering Group), which is made up of representatives from a range of local and national bodies, and meets regularly to review the management of the site and its development.

On a six-yearly cycle, each country, including the UK, has to submit a Periodic Report to the World Heritage Committee on how the World Heritage Convention is being applied. This includes reports on the state of conservation of all the World Heritage sites in its territory.

UK Tentative List

Individual national governments are each responsible for nominating sites in their country from a Tentative List of future nominations. In the UK, the Department for Culture, Media and Sport (DCMS), nominates UK sites, on behalf of the government, from the UK’s Tentative List.

The devolved administrations in Scotland, Wales and Northern Ireland are responsible for choosing sites to forward to the DCMS.

After a nomination, there is an 18-month period of evaluation by one of UNESCO’s expert advisers. ICOMOS (International Council on Monuments and Sites) is responsible for cultural sites, and IUCN (International Council for Conservation of Nature) for natural ones. The UNESCO World Heritage Committee meets each year to take a decision on nominated sites.
