Pontcysyllte Aqueduct
Pontcysyllte Aqueduct is one of the world's greatest engineering achievements. It was built between 1795 and 1805 to carry the Ellesmere Canal to link the coal mines of Denbighshire to the national canal system and the heartlands of the Industrial Revolution.
The terrain presented many obstacles to the engineers, William Jessop and Thomas Telford, the greatest of which was the crossing of the Dee valley. With its nineteen spans and height of 38.4 metres, Pontcysyllte Aqueduct was the tallest aqueduct in the world for 200 years. This spectacular achievement was made possible by the pioneering use of cast iron and the aqueduct became famous as one of the symbols of the new industrial age.
