Waypoint introductions and full write-ups
1. 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.

Planning note
Castles and Town Walls of King Edward in G is where the day begins. Next is Penrhyn Slate Quarry and Bethesda.
2. 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.

Penrhyn Slate Quarry and Bethesda comes up about 21 km into the recorded legs. Next is Conwy Castle and Town Walls.
3. Conwy Castle and Town Walls
Edward I built Conwy Castle in just four years, from 1283 to 1287, as part of his campaign to subdue the Welsh, and the result is one of the most impressive medieval fortresses in Europe. Designed by the master mason James of St George, it stands on a rock above the estuary of the Conwy river, with eight massive towers and high curtain walls, and the town below is still enclosed by its original walls, with twenty-one towers and three gateways. Walking along the walls gives superb views of the town, the castle, the estuary and the mountains of Snowdonia. The castles and town walls of King Edward in Gwynedd were inscribed on the UNESCO list in 1986.
