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)

Beaumaris Castle (/bjuːˈmærɪs/ bew-MAR-is; Welsh: Castell Biwmares Welsh pronunciation: [kastɛɬ bɪuˈmaːrɛs]), in Beaumaris, Anglesey, was built as part of Edward I's campaign to conquer north Wales after 1282. Plans were probably first made to construct the castle in 1284, but this was delayed due to lack of funds and work only began in 1295 following the Madog ap Llywelyn uprising. A substantial workforce was employed in the initial years under the direction of James of St George. Edward's invasion of Scotland soon diverted funding from the project, however, and work stopped, only recommencing after an invasion scare in 1306. When work finally ceased around 1330 a total of £15,000 had been spent, a huge sum for the period, but the castle remained incomplete.

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."
