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)

While the National Slate Museum in Llanberis undergoes redevelopment, some of the museum’s activities will continue elsewhere. For example, the unique art of slate splitting and working will be demonstrated here at Penrhyn Castle for many years to come.

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.

Unfortunately other than being an old fort, I was unable to find any other information on this very old looking abandoned building. Please let me know if you have any further information.
