June 30, 2025, Penrhyn Castle

Penrhyn Castle’s dominant stone façade belies more than its internal red-brick construction. Built in the early 19th century, its formidable architecture, opulent interiors and art collection draw on a long history of sugar and slate fortunes, social unrest and the longest-running labour dispute in British history. Owned by the Pennant family, Penrhyn is a prime example of how wealth derived from slavery has shaped Welsh buildings and local labour history. Richard Pennant, a staunch anti-abolitionist, used his fortune – acquired from slave-owning sugar plantations in Jamaica – to fund roads, railways, schools, hotels, workers’ cottages, churches and farms in North Wales. The Penrhyn Slate Quarry and Port Penrhyn, founded by the Pennants, dominated the Welsh slate industry for almost 150 years. Penrhyn Castle’s vast rooms, rich neo-Norman architecture and opulent furnishings are steeped in this colonial history. Penrhyn Castle is situated on the Menai Strait, with the peaks of the Eryri (Snowdonia) in the background, overlooking the quarry and harbour from which the slate was exported all over the world. It is surrounded by wooded and open parkland, ideal for exploring, and a walled garden that predates the castle and provides a peaceful haven for relaxation. (National Trust)

Castell Caernarfon is recognised around the world as one of the greatest buildings of the Middle Ages. This fortress-palace on the banks of the River Seiont is grouped with Edward I’s other castles at Conwy, Beaumaris and Harlech as a World Heritage Site. But for sheer scale and architectural drama Caernarfon stands alone. Here Edward and his military architect Master James of St George erected a castle, town walls and a quay all at the same time. This gigantic building project eventually took 47 years and cost a staggering £25,000. The castle was born out of bitter war with Welsh princes. So of course its immense curtain walls and daunting King’s Gate were designed to withstand assault. But the polygonal towers, eagle statues and multi-coloured masonry sent a more subtle message.

July 13, 2023, Dolbadarn Castle

Dolbadarn Castle controlled an important route into the heartland of medieval Gwynedd and was close to rich cattle pastures that provided food and income. Begun in the 1220s, the castle was built in ten years. The round tower consisted of two floors with comfortable accommodation over a basement and was a princely castle... The builder Llywelyn ab Lorwerth died in 1240, and despite his efforts to secure a peaceful succession in Gwynedd, a struggle began that did not find a clear winner until 1255. Llywelyn's grandson, Llywelyn ap Gruffudd, defeated his brothers in battle and became Prince of Gwynedd. But they still posed a threat, and Llywelyn held Owain Goch, his eldest brother, prisoner in Dolbadarn. Here he was held captive for twenty-two long years. The 13th-century poet Hywel Foel ap Griffri described Owain as "a man in the tower, long a guest."

A beautiful, large Castle with many towers you can gogo up to have a great view of the surrounding area. A very rewarding destination for any tour. if you go in, plan at least 1-2 hours to go everywhere, or just admire the walls from outside.
