Pontcysyllte Aqueduct is a Late Georgian aqueduct and navigable canal that carries the Llangollen Canal across the Dee Valley near Llangollen in Denbighshire. Designed by Thomas Telford and engineered by William Jessop, it was constructed between 1795 and 1805 as part of the Llangollen Canal system serving the industrial slate quarries and lead mines of the north Wales uplands. The structure comprises a cast-iron water trough supported on stone piers and towering 126 feet above the valley floor, making it one of the most ambitious engineering achievements of its era. The aqueduct remains in use as a navigable waterway and is regarded as an outstanding example of early industrial-age canal engineering and architectural innovation.
