Beaumaris stands on the Island of Anglesea looking across the Menai Straits and it was to control these straits that Edward I had Beaumaris built in c. 1295. It was the last of his ring of castles and was built largely in response to the rebellion of Madog ap Llywelyn. It is the largest and the most sophisticated of Edward I’s castles, probably because there was no existing structure on the site to try and build around or on top of. The native population of the area of Llanfaes was forced to move prior to the construction of the castle. It is a concentric castle with walls within walls and, something that is actually quite unusual in medieval castles, a moat that holds water. The moat was 18 feet wide and actually had a tidal port at one side that would allow for ships to come right up to the castle for trade. The curtain wall around the moat boasts 16 towers and the massive 3 quarters of an acre of the inner ward is guarded by an interior wall boasting a further 6 towers and 2 gatehouses. This castle was virtually impenetrable before the age of cannon. Ironically the castle is not complete. The towers were intended to be three stories not two.
Beaumaris has actually seen very little battle. Owain Gwndyr’s supporters held the castle for two years, 1403-1405, while the locals in the unwalled town that had developed around the castle suffered immensely in attempts to take the castle. It also did play a small role in the Civil War in the 17th century being held by royalists, then surrendered, then taken, then surrendered again. After that the castle largely stayed out of any historical events.
It is still an almost unbelievable castle to visit, not the least because it does genuinely have a moat. The town of Beaumaris in also home to the tomb of Joan Princess of Wales, illegitimate daughter of King John and wife of Llywelyn the Great. Her tomb was used as horse trough for a time, but thankfully the sarcophagus survived and can be seen in the Beaumaris parish church. For more on Joan click here.
