1. Penrhyn Slate Quarry and Bethesda
The Penrhyn Quarry is a hole you can see from a long way off. For much of the nineteenth century it was the biggest slate quarry in the world, a huge series of grey terraces cut into the mountain above Bethesda, and the roofs of half of Britain and of cities as far away as Hamburg after its great fire came from here. Its owner, Lord Penrhyn, was a rich and stubborn man, and in 1900 his quarrymen began a strike that lasted three years, one of the longest and bitterest labour disputes in British history. The community of Bethesda, named after a chapel, was split by it, and the memories are still sensitive. The whole slate landscape of north-west Wales was listed by UNESCO in 2021.

2. Castles and Town Walls of King Edward in G
Edward I built Caernarfon to be unmistakable. Begun in 1283, after his conquest of Wales, the castle rises beside the Menai Strait with polygonal towers and bands of coloured stone that echo, it is said, the walls of Constantinople, a deliberate reference to imperial power. The King wanted a seat of government as well as a fortress, and the town walls were built to enclose a planted English borough, so the whole thing was an act of colonisation in stone. UNESCO listed Edward's castles and town walls in Gwynedd in 1986, together with Conwy, Harlech and Beaumaris, and Caernarfon is the grandest of them.

3. Gorseddau and Prince of Wales Slate Quarri
High above Porthmadog, in the empty upland between Cwm Pennant and Cwmystradllyn, two abandoned slate quarries sit like ruined castles on the hillside. Gorseddau and the Prince of Wales quarry are part of the Slate Landscape of Northwest Wales, which UNESCO listed in 2021, and they tell a story of big hopes and quick failure. Gorseddau in particular was developed in the 1850s with money and ambition, a tramway and a grand multi-storey mill at Ynys-y-Pandy whose roofless stone shell still looks like an abbey. The slate turned out to be poor, and within a couple of decades the whole enterprise had wound down.
