Penrhyn Castle stands between Bangor and the Menai Strait, twenty-one kilometres west of Llandudno, and it is one of the most extraordinary buildings in Wales — a colossal neo-Norman country house built between 1822 and 1837 to look like a medieval fortress that never existed.
It was designed by Thomas Hopper for George Hay Dawkins-Pennant, and almost nothing about it is restrained. There is a great keep, a hall of Norman arcading, a slate bed made for Queen Victoria, a one-ton slate table, an eleven-metre-long dining table, and interiors of carved stone, plaster and oak worked to a degree that becomes almost oppressive.
The National Trust has owned it since 1951.
The Trust presents this directly, and it is the most important thing about the house.
Penrhyn was built on two fortunes.
Slate. The Penrhyn Quarry at Bethesda, a few miles inland, was for a time the largest slate quarry in the world. It roofed much of industrial Britain and a good part of the world beyond. It was also the site of the Great Strike of 1900–03 — the longest industrial dispute in British history, three years in which the quarrymen and the Penrhyn family fought a war of attrition that broke families, split the town of Bethesda permanently, and drove emigration.
Sugar and slavery. The Pennant family owned sugar plantations in Jamaica worked by enslaved people. Richard Pennant, the first Baron Penrhyn, was a leading parliamentary opponent of abolition, and the family received compensation — as slave owners, not as the enslaved — after the abolition of slavery in the British colonies in 1833. That money went into the quarry, the estate and this building.
The Trust’s interpretation says all of this plainly, and the house is more interesting for it. Penrhyn is a monument to nineteenth-century industrial and colonial wealth, built to look like something else entirely.
The Grand Staircase, which took ten years to carve and is the single most astonishing thing in the building.
The Great Hall, arcaded and top-lit, on a scale that has to be stood in.
The Library and Drawing Room, with Hopper’s furniture designed for the rooms.
The art collection — Rembrandt, Canaletto, Gainsborough and a strong holding of Old Masters.
The slate bed, made for Queen Victoria’s visit in 1859. She did not use it.
The Victorian kitchens, extensive and complete.
The Railway Museum in the stable block, with locomotives from the quarry lines.
The gardens — walled garden, terraces, a Bog Garden, a fine tree collection and views to Snowdonia and across the Menai Strait to Anglesey.

The Penrhyn slate quarry at Bethesda and sugar plantations in Jamaica worked by enslaved people. The National Trust’s interpretation covers both directly.
