Waypoint introductions and full write-ups

  1. 1. Beaumaris Castle

    Beaumaris is often called the most perfect castle never finished. Edward I began it in 1295 on the shore of Anglesey, at the northern entrance to the Menai Strait, as the last of his great chain of fortresses built to hold down Wales after his conquest. His architect, Master James of St George, designed it as a perfectly symmetrical concentric castle: an inner ring of high walls and towers, an outer ring of lower walls, and a moat linked to the sea so that supply ships could sail up to a dock at the gate. Money ran out, the Scottish wars took priority, and the towers never reached their planned height. Even so, it is a masterpiece of military design, and with the castles of Conwy, Caernarfon and Harlech it is listed by UNESCO.

  2. 2. Nantlle Valley Slate Quarry Landscape

    Look at the Nantlle valley from the road and you see a green bowl with a ragged grey edge, as if someone had bitten the mountain. It is a place where the quarrying went down instead of along. The pits here are enormous, cut deep below the level of the lakes, with sheer sides, and the biggest of them, the Dorothea, became a flooded hole of cold green water. On the skyline, tips of waste slate lean against each other like broken plates. This is part of the slate landscape of north-west Wales that UNESCO listed in 2021, and the quarries here are among the oldest in the area, producing roofing slate from the eighteenth century and earlier.

    Nantlle Valley Slate Quarry Landscape comes up about 38 km into the recorded legs. Next is Conwy Castle and Town Walls.

  3. 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.

  4. 4. The Slate Landscape of Northwest Wales

    Llanberis sits at the foot of Snowdon, Yr Wyddfa in Welsh, beside the lake of Llyn Padarn, and across the water a whole mountainside has been carved into giant terraces. This is the Dinorwic quarry, once one of the largest slate quarries in the world, where thousands of men worked until it closed in 1969, splitting slate for roofs across Britain and beyond. The galleries climb the mountain in steps, with inclines, ruined buildings and waste heaps everywhere, a landscape both scarred and strangely beautiful. In 2021, UNESCO inscribed the Slate Landscape of Northwest Wales, recognising the quarries, villages, railways and harbours that made this region the slate capital of the world.

    Planning note

    The Slate Landscape of Northwest Wales, about halfway. Next is Harlech Castle.

  5. 5. Harlech Castle

    When Edward I built his castles in Wales, he was not interested in subtlety. Harlech, raised between 1283 and 1289 by the master mason James of St George, sits on a rocky crag above the dunes of Cardigan Bay, with concentric walls, massive gatehouse and round towers that still look ready for a siege. It is one of the castles of Edward I in Gwynedd listed by UNESCO, together with Caernarfon, Conwy and Beaumaris. The sea once came almost to the foot of the rock, and a staircase down the cliff allowed the garrison to be supplied by boat; the coast has since moved, and now there is a broad plain of dunes and a golf course between the castle and the water.
