Pontcysyllte Aqueduct and canal envelopes a collection of amazing British Engineering feats that were accomplished during the British Industrial Revolution. The canal carried water borne transport from the English lowlands into the rugged terrain of the North Wales Hills, using new techniques to cross two major river valleys and the ridge between them.
It was built between 1795 and 1808 by Thomas Telford and William Jessop. Through their dynamic partnership the canal became a testing ground for new ideas that became engineering practice throughout the rest of the world. It was named a World Heritage Site in 2009. To be named on the World Heritage List, sites must be of outstanding universal value and meet specified criteria.
