World Heritage Site
The World Heritage Site at Pontcysllte
When UNESCO added the site to its World Heritage List in 2009 - a list that includes the Taj Mahal, The Pyramids and the Great Wall of China - it meant Pontcysllte officially joined the world's elite.
The experts at UNESCO basically agreed that Pontcysyllte represented a 'masterpiece of human creative genius' and that it was an outstanding example of a construction that 'illustrated a significant stage in human history.'
So, in a nutshell, being a World Heritage Site means being part of an exclusive club. A group of sites that are recognised for their 'outstanding universal value' in some form or another
