North Wales is a region steeped in heritage, shaped by both natural beauty and human endeavour. From mighty fortresses to scenic landscapes shaped by centuries of industry, the area boasts a remarkable collection of UNESCO World Heritage Sites – each one offering visitors a unique glimpse into the past. Whether you’re a seasoned history lover or a casual explorer, staying at the Black Boy Inn in Caernarfon places you in prime position to experience them all.
Caernarfon Castle – A Crown Jewel of Medieval Europe
Right on our doorstep lies one of the most impressive medieval structures in the UK. Caernarfon Castle, a cornerstone of Edward I’s “Iron Ring” of castles, was designed to assert English power over Wales – but today it stands as a proud symbol of Welsh resilience and national identity. Its distinctive polygonal towers, elaborate defences, and riverside location make it a must-visit for guests staying at the inn.
This fortress forms part of the wider “Castles and Town Walls of King Edward in Gwynedd” UNESCO designation, which also includes Conwy, Harlech, and Beaumaris – all easily visited as day trips from Caernarfon.
The Slate Landscape of Northwest Wales
Added to the World Heritage List in 2021, this newer designation celebrates the dramatic slate quarries and historic towns that fuelled a global industry and shaped communities for generations. Key sites include Dinorwig Quarry near Llanberis, the Nantlle Valley, and the iconic Penrhyn Quarry. These sites tell the story of Welsh workers whose craftsmanship and labour made North Wales slate a worldwide name.
Visitors can explore the history hands-on at locations like the National Slate Museum in Llanberis or take a scenic ride on the Welsh Highland Railway, which once hauled slate from quarry to coast.
Pontcysyllte Aqueduct and Canal – An Engineering Wonder
Just over an hour from Caernarfon, the Pontcysyllte Aqueduct in Llangollen is a jaw-dropping feat of 19th-century engineering. Designed by Thomas Telford and opened in 1805, this navigable aqueduct carries the Llangollen Canal high above the River Dee and is the tallest of its kind in the world. A walk or narrowboat ride across the aqueduct offers panoramic views and a memorable sense of height and scale.
Planning Your Stay
With its central location and centuries-old charm, the Black Boy Inn makes an ideal base for exploring these UNESCO-listed wonders. After a day of discovery, return to our cosy medieval Caernarfon hotel for a hearty meal, a pint of local ale, and a peaceful night’s rest. We offer a loyalty scheme for regulars, and a selection of quality rooms.
Caernarfon itself is more than just the gateway to these UNESCO sites – it’s a destination in its own right. With its cobbled streets, waterfront views, and thriving independent shops and eateries, the town offers a charming blend of history and local life. Staying in Caernarfon means you’re within easy reach of the best North Wales has to offer, all while enjoying the comforts and warm welcome of a community that proudly celebrates its heritage. Whether you’re here for the castles, the coast, or the culture, Caernarfon provides the perfect place to return to at the end of each day.
From castles and canals to quarries and coastlines, North Wales’ World Heritage Sites offer a journey through time – and we’re proud to be right at the heart of it.
