The World Heritage Sites of Wales.

From ancient fortresses to centres of great industrial innovation, the World Heritage Sites of Wales are protected by UNESCO as areas of global importance.

  • Pontcysyllte Aqueduct
    Pontcysyllte Aqueduct, Wrexham, North East Wales

    In 2009, a little more than 200 years after it was built, Pontcysyllte joined the likes of the Taj Mahal and Stonehenge on UNESCO’s World Heritage Sites list. Enjoy a horse-drawn canal trip, see the horseshow piers and be astonished by an aqueduct which holds 1.5 million litres of water. 


  • Old mining machinery at Big Pit
    Big Pit National Coal Museum in Blaenavon, South Wales Valleys

    An incredible town with an iron heart, Blaenavon grew around an ironworks in 1788. These days it is home to the Big Pit: National Coal Museum, the Pontypool and Blaenavon Railway and, of course, the Blaenavon Ironworks. Set on a hillside, it’s the place to explore a proud industrial past.

  • Interior courtyard of Caernarfon Castle, Gwynedd

    Caernarfon Castle courtyard, Snowdonia

    Edward I wasn’t messing around when he built this polygonal 13th century castle on a former Roman fort. Part of the coastal World Heritage Site, the mighty Caernarfon remains one of the most visually arresting sights you’ll ever see. Exhibition rooms also feature at a landmark to stir the senses.

  • Outer walls and towers of Harlech Castle
    Harlech Castle, Snowdonia

    Such is its beautiful setting in Snowdonia, it’s hard not to believe some sympathetic positioning was afoot when it was built by Edward I more than 700 years ago. The views are unbeatable, but the massive inner walls of the fortress and battlements are equally impressive. Made for the camera.

  • Beaumaris Castle
    Beaumaris Castle, Anglesey

    The concentric designs and arching masonry of Beaumaris make it an enchanting place to visit, built as a royal palace for Edward I and realised for its architecture with World Heritage Site status. It was actually unfinished but, with views like these over the mountains, you’d never know it.

  • Conwy Castle

    Conwy Castle, North Wales

    Perched on a rock against the backdrop of Snowdonia, Conwy has an indisputably magical feel. Some consider it the finest castle Edward I built, and the mesmerising views from the battlements are particularly famed within the walled town. Great halls, private chapels and royal chambers wind through this medieval marvel.
