With the application of the new technologies of cast iron, Pontcyscyllte Aqueduct was a highly innovative monumental structure and its enduring legacy is due to the brilliance of Jessop and Telford’s design. Eighteen tapering stone piers carry a narrow trough of iron plates for a distance of 307m. There is only 25mm between the water inside and the thin air outside the metal plates. It is 38.4m from the water level of the canal to the river below. Pontcysyllte remained the tallest navigable aqueduct in the world for 200 years. It was only superseded in the twenty-first century by aqueducts for boat lifts in Belgium and China.
