About Harlech

Harlech is a small town on the southern coast of Eryri, dominated absolutely by Harlech Castle — one of Edward I's Iron Ring of conquest, built from 1283 by master castle-builder James of St George. The castle sits on a 60-metre sheer rock that gave it an almost impregnable position: the town and sea below to the west, the Rhinog mountains rising to the east, and the peaks of Snowdonia visible on the northern horizon. The rock was originally lapped by the sea on its western side — a combination of land reclamation and falling sea levels has since moved the coastline more than a mile to the west, leaving the Morfa Harlech dune system where the water once was.

Harlech Castle is a UNESCO World Heritage Site and one of the most dramatically sited castles in Britain. The gatehouse is enormous — a double-towered structure that was effectively a self-contained fortress — and the curtain walls and corner towers command the rock on all sides. The castle was garrisoned in the Wars of the Roses from 1461 to 1468 in the longest siege in British history, finally surrendering after food ran out — the episode commemorated in "Men of Harlech". Cadw manages the site.

Below the castle, Morfa Harlech National Nature Reserve extends to a long sandy beach backed by extensive dune grassland. The Rhinog mountains rise steeply behind the town, offering demanding hill walking on one of the least-visited ranges in Snowdonia. The Cambrian Coast Line railway serves Harlech, running between Pwllheli and Shrewsbury along one of the finest coastal railway routes in Britain.
