Ymddiheuraf, does dim ar gael yn Gymraeg.

Pontcysyllte Aqueduct and canal consists of a continuous group of civil engineering features from the heroic phase of transport improvements during the British Industrial Revolution.  The canal brought water borne transport from the English lowlands into the rugged terrain of the Welsh uplands, using innovative techniques to cross two major river valleys and the ridge between them.

It was inscribed as a World Heritage Site in 2009 and to be included on the World Heritage List. Sites must be of outstanding universal value and meet at least one out of ten selection criteria.
