Wales may be one of the smallest countries in the United Kingdom but still has its own rich traditions and history. Castles are a major part of this history and can be found all over the stunning Welsh landscape. There are well over 400 castles in Wales, the most castles per square mile than anywhere else in the world.

Most of these imposing and magnificent buildings were built after Wales fell to England after Dafydd, the last Prince of Wales, was executed by King Edward I in 1283. The victorious king spent decades building castles around the countryside to both overlook and protect the lands and also keep the Welsh subjugated and faithful to English rule.

The colossal Caernarfon Castle was also built in the 13th century by King Edward I. Set along the sea, the views from its towers are absolutely breathtaking.

3. Harlech Castle

Harlech, Wales, United Kingdom

Another of Edward I’s castles, Harlech Castle was built between 1283 and 1295. Set amidst the stunning Welsh countryside, this concentric sandstone castle was besieged during the Wars of Roses in the 15th century, and again during the English Civil War, but the damage was never repaired.
