Pontcysyllte Aqueduct & Trevor Basin Visitor Centre

Pontcysyllte Aqueduct and the Llangollen Canal sit in a beautiful area of North East Wales, set within an Area of Outstanding Natural Beauty and a Site of Special Scientific Interest.

Pontcysyllte Aqueduct and 11 miles of the Llangollen Canal received UNESCO World Heritage Site status in 2009. The experts at UNESCO believe that Pontcysyllte represents a 'masterpiece of human creative genius' and that it is an outstanding example of construction that 'illustrates a significant stage in human history.'

Trevor Basin Visitor Centre is located next to the aqueduct and houses a collection of historical artifacts dating back to the construction of the aqueduct. Visitors can also enjoy the ‘Stories from the Aqueduct’ video, ‘How they built the aqueduct’ animation video, children’s activity area including a wooden ‘build the aqueduct’ and gift shop. Our friendly staff and volunteers are always on hand to help.
