Gwynedd is the second-largest county in Wales and one of its least crowded, which is not a paradox so much as an honest account of what mountains do to settlement patterns. The county covers the old historic counties of Caernarfonshire and Merionethshire, and most of what lies between them is Eryri — Snowdonia — a tangle of hard, ancient rock carved out by glaciers into ridges, cwms, and sudden steep valleys that tend to ambush visitors expecting something more pastoral.

At the centre of it all rises Yr Wyddfa, the highest point in England and Wales at 1,085 metres. The name is old and worth knowing: it means the grave, or more precisely the burial mound. One tradition holds that Rhita Gawr, a giant slain by King Arthur, lies under the summit cairn. A mountain that names itself as a tomb is making a specific kind of statement, and Gwynedd tends to deal in those.

From the high ground the county reaches west and south to a long, indented coastline. The Llŷn Peninsula jabs thirty miles into the Irish Sea like a pointed finger, its southern coast still bearing the name Porth Neigwl — Hell's Mouth — earned by generations of sailors who found themselves embayed in its south-westerly swell with no good options. Surfers now find it useful for the same reasons. The peninsula was once the main route for pilgrims heading to Bardsey Island at its tip, and the names of the small ports along the way encode that history quietly: Porth Meudwy, the Port of the Hermits, is where the boat still leaves.

Bardsey Island — Ynys Enlli in Welsh, meaning the Island in the Currents — lies two miles off the westernmost point of Llŷn across one of the stronger tidal races in European waters. The medieval pilgrims thought three journeys there equivalent to one to Rome. The island has a year-round population of three. In 2023 it became the first site in all of Europe to receive International Dark Sky Sanctuary certification, joining sixteen other sites worldwide. The medieval saints and the astronomers have evidently agreed on something.

Inland, the largest natural lake in Wales, Llyn Tegid — Bala Lake — sits in the east of the county, long and cold and containing a fish found nowhere else in the world: the gwyniad, a pale, deep-water relative of the salmon that has been trapped in the lake since the last ice age. It does not take well to nets. Most people have never seen one.

The Welsh of Gwynedd is the Welsh that Welsh-language learners are warned about. The northern dialect differs from the south in pronunciation, in vocabulary, and in a certain directness that outsiders sometimes mistake for coldness and locals would simply call accuracy. Where a southerner might say dw i eisiau, a northerner says dw i isio — two syllables fewer, and no apology offered for it.

Welsh in Gwynedd is not a heritage item. It is the language of the school run, the council meeting, the argument at the planning office, and the argument in the pub. In villages along the Llŷn Peninsula and around Caernarfon, it is still the first language of daily life in a way that has no real equivalent anywhere else in Britain. The 2021 census recorded that 64.4 per cent of Gwynedd residents could speak it — a figure that has defied a century of predictions that it would not survive.

The word panad — a shortened form of paned, a cup — is offered more often than handshakes. It means tea, almost certainly, and refusing it is a social act requiring explanation. Mynadd means patience, or the will to endure a tedious task, and the phrase does gen i ddim mynadd — I have no mynadd for this — carries a weight of resigned local feeling that translation does not quite capture. Iawn? — literally "alright?" — functions as greeting, farewell, and conversational filler simultaneously. The expected answer is also iawn.

Underlying all of this is the cynghanedd, the system of strict-metre poetry that has no real equivalent in any other European tradition. It involves rules of internal rhyme, consonant repetition, and rhythmic stress so intricate that it takes years to learn and a lifetime to master. Quarrymen in the slate villages would compete at local eisteddfodau in strict cynghanedd verse after their shifts. Hedd Wyn, who was among the best of them, mastered the rules before his twelfth birthday. He was a shepherd, not a quarryman, but the culture was the same: poetry as a thing you did, not a thing you consumed.

By the 1890s the slate quarries of Gwynedd were producing nearly a third of all roofing slate used anywhere in the world. The roofs of Westminster Hall, the Royal Exhibition Building in Melbourne, and Copenhagen City Hall were all dressed with Gwynedd slate. The Penrhyn quarry near Bethesda was the largest in the world — nearly a mile long and 370 metres deep — worked by close to three thousand men. The neighbouring Dinorwic quarry was not far behind. What came off those terraced hillsides, split and trimmed by men with intimate knowledge of the grain of the rock, covered the industrial cities of Britain as they expanded outward through the nineteenth century.

The quarrymen had their own culture, and it was not a simple one. The chapels they built with their pennies — the working families of Bethesda were Nonconformist, Welsh-speaking, and Liberal, in contrast to the Anglican, English-speaking, Conservative quarry owners — funded what became the University of Wales. They organised eisteddfodau in their lunch breaks. The men worked in small groups called bargains, negotiating their pay according to the difficulty of the rock face they'd been assigned; the system gave them a degree of autonomy that the owners increasingly resented.

The great collision came in November 1900, when 2,800 quarrymen walked out of the Penrhyn quarry and did not return for three years. It remains the longest dispute in British industrial history. Lord Penrhyn — whose family's wealth also derived from Jamaican sugar plantations worked by enslaved people, a fact he did not find inconsistent with his position — refused to recognise the North Wales Quarrymen's Union and declined every negotiation. Those who refused to cross the picket line wrote or placed cards in their windows: Nid oes bradwr yn y tŷ hwn. There is no traitor in this house. Those who eventually went back were marked as bradwyr — traitors — and the social scarring lasted generations. Some streets in Bethesda are still identified locally by whether the households in them broke the strike.

The men lost. By November 1903, with the union's funds exhausted and families hungry, the remaining strikers returned on Lord Penrhyn's terms. About 2,000 had already left the valley entirely, most for the coalfields of South Wales. The community never recovered its former size. Lord Penrhyn had nicknamed his two daughters Sugar and Slate, after his two sources of income. The daughters, presumably, did not choose their names.

As for the slate itself: it came down from Blaenau Ffestiniog to the port at Porthmadog on the Ffestiniog Railway — the oldest surviving railway company in the world, incorporated by Act of Parliament in 1832. The loaded wagons ran by gravity, controlled by brakemen who rode them down the mountain. Horses rode in special carriages at the rear of each train to haul the empties back up. The company was so small and so peculiarly Welsh that when the railways were nationalised in 1947, the Festiniog Railway was simply forgotten about. It remains independent to this day, its legal title still containing only one F — as in the Act — which cannot now be changed without a new Act of Parliament.

Rhyfel — War — was composed by Hedd Wyn during the weeks before and after his regiment shipped to France in the summer of 1917. It is his most-quoted poem, and perhaps his most direct. He wrote in a tradition of strict Welsh metre that demanded precision in every syllable, and this short lyric demonstrates how the cynghanedd works even in grief and anger: the consonants chime against themselves, the lines fold back on their own sounds. In the last stanza the image of harps hung on willow branches echoes Psalm 137 — the exiles of Babylon weeping by the river, unable to sing — and the harps of Welsh culture and the harps of scripture become the same harps.

He was killed on 31 July 1917. The poem was submitted to the Eisteddfod under the name Fleur-de-lis. The Archdruid called that name three times, in a hall in Birkenhead, and the silence that followed was the answer.

A plain rendering in English: Woe that I live in an age so bleak, with God retreating beyond the far horizon; in his wake, man — lord and peasant alike — raises his own grim authority. Feeling God withdraw, he lifted his sword to kill his brother; the sound of fighting is in our hearing, and its shadow falls on the poor cottages. The old harps that once were played hang now on the willow branches over there, and the cries of the boys fill the wind, their blood mingled with the rain.
