Pontcysyllte aqueduct has become the UK’s latest UNESCO World Heritage site - and only the third in Wales
The 200-year old structure in North Wales was built by Thomas Telford and William Jessop between 1795 and 1805, is the longest and highest aqueduct in Britain.
Pontcysyllte was Britain’s only nomination at the 33rd session of Unesco’s World Heritage Committee and is now the 28th such heritage site in the UK. It joins a list of approximately 900 properties deemed to have outstanding universal value for humanity, including the Great Wall of China, the Taj Mahal and Stonehenge.
Around 16,000 canal boats cross the aqueduct every year, which sits 126 feet above the River Dee.
