Beaumaris Castle

Beaumaris Castle on the Isle of Anglesey is a late 13th-century concentric fortress widely regarded by military historians as a near-perfect example of its type. Edward I ordered its construction in 1295 as part of his campaign to consolidate English control over Wales, but funding dried up before completion — making it, paradoxically, one of the most instructive castles in Europe. The unfinished state preserves the planning logic in plain sight: a square inner ward, a lower outer curtain wall with its own towers, and a heavily fortified gatehouse doubling as a keep form a textbook layered defence. The castle has been a UNESCO World Heritage Site since 1986 as part of the 'Castles and Town Walls of King Edward in Gwynedd' inscription. From the battlements, visitors look out across the Menai Strait toward the Snowdonia mountains, the island setting adding to the site's quietly atmospheric character.
