The Pontcysyllte Aqueduct and Canal is a World Heritage Site in northeastern Wales. It comprises the 1,007-foot (307-meter) aqueduct, which is linked to a canal, giving a total length of 18 km.

The Pontcysyllte Aqueduct is lauded as a feat of early 19th century engineering. It carries the Llangollen Canal, between Llangollen parish and the town of Trevor. The aqueduct is 11 feet wide and 5.25 feet deep. It stands on masonry piers that are 126 ft (38m) above the river, making it the highest and longest aqueduct in Britain.

The Pontcysyllte Aqueduct was built by Scottish civil engineer Thomas Telford and English civil engineer William Jessop. They designed the canal trough of cast iron rather than masonry. This substantially reduced its weight while also made the structure look more elegant. The aqueduct was constructed without locks, a remarkable achievement and widely applauded as a masterpiece of creative genius. Pontcysyllte Aqueduct and Canal was inscribed as a World Heritage Site during the 33th session of the World Heritage Committee in Seville, Spain, on 22 - 30 June, 2009.
