Summary

Situated in north-eastern Wales, the 18 kilometre long Pontcysyllte Aqueduct and Canal is a feat of civil engineering of the Industrial Revolution, completed in the early years of the 19th century. Covering a difficult geographical setting, the building of the canal required substantial, bold civil engineering solutions, especially as it was built without using locks. The aqueduct is a pioneering masterpiece of engineering and monumental metal architecture, conceived by the celebrated civil engineer Thomas Telford. The use of both cast and wrought iron in the aqueduct enabled the construction of arches that were light and d strong, producing an overall effect that is both monumental and elegant. The property is inscribed as a masterpiece of creative genius, and as a remarkable synthesis of expertise already acquired in Europe. It is also recognized as an innovative ensemble that inspired many projects all over the world.

This site is a trans-national cultural site as part of the site is in England and part is in Wales. It is located at N52 58 13 W3 5 16 and measures 105 hectares. Its buffer zone measures 4,145 hectares.

There is a World Heritage Site Management Plan for the World Heritage Site (2009) and implementation of the objectives and action plan is undertaken by a World Heritage Site coordinator in Wrexham County Borough Council. A Steering Group made up of key stakeholders oversees World Heritage activities.

Criteria

This entry is compiled from information provided by UNESCO who hold the official record for all World Heritage Sites at their Paris Head Quarters. This entry is provided for information only and those requiring further assistance should contact the World Heritage Centre at UNESCO.

Criterion (i): The Pontcysyllte Aqueduct is a highly innovative monumental civil engineering structure, made using metal arches supported by high, slender masonry piers. It is the first great masterpiece of the civil engineer Thomas Telford and formed the basis of his outstanding international reputation. It bears witness to the production capacities of the British ironmaking industry, which were unique at that time.

Criterion (ii): The intensive construction of canals in Great Britain, from the second half of the 18th century onwards, and that of the Pontcysyllte Canal in particular in a difficult region, bear witness to considerable technical interchanges and decisive progress in the design and construction of artificial waterways.

Criterion (iv): The Pontcysyllte Canal and its civil engineering structures bear witness to a crucial stage in the development of heavy cargo transport in order to further the Industrial Revolution. They are outstanding representatives of its new technical and monumental possibilities.
