With its waterside location, polygonal towers, and UNESCO World Heritage Site status, Caernarfon Castle is not to be missed if you happen to be in the county of Gwynedd in north Wales. Located on the River Seiont, the castle has been around for hundreds of years, and has had a number of significant roles throughout Welsh history. The beautiful architecture and ancient legends of the castle make it a truly magical place to visit, and it is considered to be the to pick of north Wales castles.

Caernarfon Castle started its life all the way back in the 11th century, where it stood as a standard motte and bailey castle, a structure that was popular at the time. The motte, or man-made hill, made it easier for the occupants of the castle to see enemies approaching, and the bailey, or enclosed stone courtyard, was another line of defence. There would also have been a stone keep, or tower, built inside the bailey, At Caernarfon Castle you can still see parts of this structure, although it was altered over the years. In the 13th century, following a war between England and Wales and the death of the Welsh leader Llywelyn ap Gruffudd, King Edward I won, and began to take charge of castles across northern Wales. Caernarfon Castle, while it was already a motte and bailey castle, was restructured and the motte was made into a new Edwardian Castle. The castle was a feat of architecture, and was designed by James of Saint George, who was responsible for the huge Eagle Tower and many of the significant design points of the building. The castle was so grand it began to expand into areas of the city of Caernarfon, and some people even had to leave their houses in order for them to be replaced by the castle. New city walls were built, and timber apartments were made so King Edward could visit with his wife, Queen Eleanor. It was around this time that the most impressive of all the towers, the Eagle Tower, was completed, so the King and Queen could stay there for the birth of their child. The tower had walls that were 18 feet thick, and had multiple turrets that were decorated with stone eagles.

However, there was more unrest between the English and Welsh, and Caernarfon was in danger due to its role as an English fortress. When a rebellion led by the Welsh prince Madog ap Llywelyn came about at the end of the 13th century, Caernarfon was attacked. The town was sacked and the castle set alight, with fire destroying much of the town. The English took the castle back a year later in 1295, and Edward continued to build up the castle and town. To this day, most of what we can see of the castle is from this period, although many of the inner buildings no longer exist.

Over the next few hundred years, there continued to be conflict between the successors of King Edward and the Welsh princes who objected to the castle town of Caernarfon, although the castle itself stayed in relatively good condition. When the Tudors took the English throne in the 15th century, tensions were alleviated between the Welsh and English, as the Tudors came from Welsh lineage. The castle even survived the English civil war, despite being under siege no less than three times. While the timber and roofed areas of the castle had begun to wear by the 17th century, the stone defences were still effective, and their sturdiness is what allows us to still visit them to this day. Following the civil war, the castle lay neglected for a number of years, but was eventually restored in the late 19th century. The investiture of Edward VIII to become Prince of Wales took place in the castle in 1911, and later Prince Charles in 1969. Over the years, Caerarfon Castle certainly earned its status as a UNESCO World Heritage Site, and has lasted over 700 years since its original construction. With tales of Welsh princes and an old castle town, and rumoured to have been based on the Walls of Constantinople when it was built, this castle is filled with mystery and legend. Today, the castle attracts hundreds of thousands of people from all over the world every year, who come to see the famous castle set in the ancient town walls.
