Welsh castles of Edward I

The four UNESCO castles of the iron ring, in two days.

When Edward I conquered Gwynedd in 1283 he commissioned four monumental castles — Conwy, Caernarfon, Harlech and Beaumaris — to lock the north Welsh coast under English rule. Together they form a single UNESCO World Heritage Site, and the largest and most ambitious medieval military architecture in Britain. The four sit within an hour's drive of each other and can be seen in two unhurried days.
