Studley Royal Park in the context of Fountains Hall

The United Nations Educational, Scientific and Cultural Organization (UNESCO) World Heritage Sites are places of importance to cultural or natural heritage as described in the UNESCO World Heritage Convention, established in 1972. Cultural heritage consists of monuments (such as architectural works, monumental sculptures, or inscriptions), groups of buildings, and sites (including archaeological sites). Natural features (consisting of physical and biological formations), geological and physiographical formations (including habitats of threatened species of animals and plants), and natural sites which are important from the point of view of science, conservation or natural beauty are defined as natural heritage. The United Kingdom ratified the convention on 29 May 1984, making its sites eligible for inclusion on the list.

There are 35 World Heritage Sites in the United Kingdom and the British Overseas Territories. Out of these sites, one site is located in both England and Scotland (the Frontiers of the Roman Empire), eighteen are exclusively in England, seven in Scotland, four in Wales, two in Northern Ireland, and one in each of the overseas territories of Bermuda, Gibraltar, the Pitcairn Islands, and Saint Helena. The first sites in the UK to be inscribed on the World Heritage List were Giant's Causeway and Causeway Coast; Durham Castle and Cathedral; Ironbridge Gorge; Studley Royal Park including the Ruins of Fountains Abbey; Stonehenge, Avebury and Associated Sites; and the Castles and Town Walls of King Edward in Gwynedd in 1986. The most recent site listed was Gracehill, as a part of transnational site Moravian Church Settlements, in 2024. Among the 35 sites, 29 are listed for their cultural significance, five for their natural significance, and one, St Kilda, for both. In addition, there are five sites on the tentative list. The UK has served on the World Heritage Committee once.

Fountains Abbey is a ruined Cistercian monastery near Ripon in North Yorkshire, England. It was founded in 1132 under the direction of Thurstan, archbishop of York, and over the next four centuries became one of the wealthiest monasteries in England thanks to its large and diverse landholdings. The monastery was dissolved in 1539 as part of the English Reformation and its estates sold. Fountains Abbey is now within Studley Royal Park, a landscaped garden created in the eighteenth century.

Even in its current state, Fountains is described by Historic England as "the best preserved of English abbeys and [...] the finest picturesque ruin." The majority of the buildings were constructed in the Romanesque and Early English Gothic style between 1170 and 1247, with significant additions in the late fifteenth and early sixteenth centuries. The abbey church and many of the claustral buildings survive, including the chapter house, refectory, and lay brothers' dormitory, as well as ancillary structures such as the guest houses, abbey mill, and bridges.
