The supreme achievement of canal engineering, the Pontcysyllte Aqueduct over the Vale of Llangollen, through which the river Dee flows, is undoubtedly one of Thomas Telford’s finest works. Nineteen iron spans of 54ft give a total length of 1007ft at a maximum height of 127ft above the river. This object is a single arch (in three sections) of one of the spans that was fractured after prolonged settlement of the impressive embankment, also of Telford’s design. Now replaced with welded steel, this cast iron arch was acquired from the British Waterways Board in 1977 and has been in storage ever since.
