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.

Before the English built the town of Conwy, Aberconwy Abbey, the site was occupied by a Cistercian monastery favoured by the Welsh princes,[3] as well as the location of one of the palaces (called llys) of the Welsh princes. From Conwy: "the oldest structure is part of the town walls, at the southern end of the east side. Here one wall and the tower of a llys [palace/court house] belonging to Llywelyn the Great and his grandson Llywelyn ap Gruffydd have been incorporated into the wall. Built on a rocky outcrop, with an apsidal tower, it is a classic, native, Welsh build and stands out from the rest of the town walls, due to the presence of four window openings. It dates from the early 13th century and is the most complete remnant of any of his Llys." The location also controlled an important crossing point over the River Conwy between the coastal and inland areas of North Wales, that Deganwy Castle for many years had defended.
