Caernarfon is a historic town in northwest Wales, located on the eastern shore of the Menai Strait, which separates the Isle of Anglesey from the mainland. It is most famous for Caernarfon Castle, a majestic fortress built by King Edward I in the late 13th century as part of his campaign to conquer Wales. The castle is one of the best-preserved medieval fortresses in Europe and is a UNESCO World Heritage Site.
The town itself has a rich cultural heritage, with a predominantly Welsh-speaking population, giving it a strong sense of local identity. The narrow, winding streets of the old town are lined with traditional stone buildings, quaint shops, and cozy pubs. Caernarfon is also known for its scenic waterfront, with views across the Menai Strait and towards the mountains of Snowdonia.
Caernarfon has played an important role in Welsh history and culture. It was the site where Prince Charles was invested as Prince of Wales in 1969, continuing a tradition that dates back to the medieval period. The town’s atmosphere reflects a blend of its historical significance and modern-day vibrancy, making it a popular destination for visitors interested in Welsh history, culture, and natural beauty.
Beyond the castle, visitors can explore the surrounding region, including the nearby Snowdonia National Park, offering outdoor activities such as hiking, climbing, and exploring the rugged Welsh landscape.


Caernarfon’s origins and development are deeply rooted in the history of Wales, with influences from Roman, Norman, and medieval periods shaping its character.
Roman Origins:
The area around Caernarfon was first settled during the Roman occupation of Britain. The Romans established a fort called Segontium around AD 77–78 on a hill just outside the present-day town. Segontium was built to control the local Celtic tribe, the Ordovices, and to protect the Roman Empire’s interests in the region. The fort remained an important military base until the Roman withdrawal from Britain in the early 5th century.
Early Medieval Period:
After the departure of the Romans, the site became part of the Kingdom of Gwynedd, an early Welsh kingdom. The area retained its strategic importance due to its location near the Menai Strait and its proximity to the mountains of Snowdonia. It was during this time that Caernarfon became associated with Welsh royalty, particularly during the reign of Llywelyn the Great in the 13th century.
Norman and Plantagenet Influence:
The town of Caernarfon as we know it today began to take shape during the Norman period. The Normans, after their conquest of England in 1066, sought to extend their control into Wales. However, it was not until the late 13th century that Caernarfon underwent significant development under the rule of King Edward I of England. Following his conquest of Wales, Edward embarked on an ambitious project to build a series of castles to consolidate his power over the Welsh.
Construction of Caernarfon Castle:
In 1283, Edward I began the construction of Caernarfon Castle, which was designed to be both a military stronghold and a symbol of English authority in Wales. The castle was built on the site of an earlier Norman motte-and-bailey structure, and its design was inspired by the imperial Roman architecture Edward had seen during his campaigns in France and Italy. The walls of the castle and the town were built simultaneously, forming a formidable defensive complex. Caernarfon Castle’s design is notable for its polygonal towers and the use of colored bands of stone, which were intended to evoke the appearance of the walls of Constantinople.
Medieval and Tudor Period:
Caernarfon quickly grew into an important administrative center for the English crown in Wales. The town was granted a charter in 1284, which allowed it to hold markets and fairs, fostering economic development. During this period, Caernarfon became a focal point for the English administration in North Wales, and the castle was used as a royal residence and a seat of government.
In 1284, Edward I’s son, the future Edward II, was born at Caernarfon Castle, and in 1301, he was invested as the first English Prince of Wales, a tradition that has continued to this day. This event marked the beginning of Caernarfon’s association with the title of the Prince of Wales.
Decline and Revival:
After the Tudor dynasty came to power in the 16th century, the strategic importance of Caernarfon Castle diminished, and the town’s prominence declined. The castle fell into disrepair, and the town became a quiet backwater.
However, in the 19th century, Caernarfon experienced a revival due to the Industrial Revolution. The expansion of slate quarrying in the nearby mountains of Snowdonia brought economic prosperity to the town, which became an important port for the export of slate. This period also saw the growth of the town’s population and infrastructure, with new buildings and roads constructed to accommodate the booming slate industry.
Modern Era:
In the 20th century, Caernarfon’s historical significance was recognized, and efforts were made to preserve its medieval heritage. The castle was restored and became a popular tourist attraction. In 1969, Caernarfon Castle was once again thrust into the spotlight when Prince Charles was invested as Prince of Wales in a grand ceremony held within its walls.
Today, Caernarfon is a thriving town that blends its rich history with modern amenities. It remains a center of Welsh culture, with a strong Welsh-speaking community, and continues to attract visitors from around the world who are drawn to its historic castle, scenic location, and cultural significance.
