Caernarfon, a historic town of around 10,000 residents, is renowned for its architecture and heritage. Its origins can be traced back to Roman times when it served as the fortification known as Segontium. However, its true prominence began in the 13th century with the construction of Caernarfon Castle under the orders of King Edward I of England.

#1 Explore Caernarfon Castle

Make sure to add Caernarfon Castle to your must-visit list when you’re in town. This incredible fortress, constructed by King Edward I in the 13th century, is part of the UNESCO World Heritage Site, Castles and Town Walls of King Edward I in Gwynedd.

Don’t miss the intriguing exhibition about the investiture of Charles as Prince of Wales, which took place at the castle in 1969.  It includes special artifacts like the throne used by Queen Elizabeth II during the ceremony, invitations that were sent, a video of the occasion, and more.  The large circular spot inside the castle marks the spot where it all took place.

While the views from the castle are truly breathtaking, keep in mind that the steps up can be narrow and steep. Take your time and proceed at a comfortable pace.

#2 See the Caernarfon Town Walls 

Don’t miss the incredible Caernarfon Town Walls while exploring the town. These remarkable medieval fortifications are part of the UNESCO World Heritage Site, Castles and Town Walls of King Edward I in Gwynedd. At first glance, I thought the town walls were part of the castle due as they are made from the same stone and quite imposing.

The East Gate was the main entrance into the walled town from inland.

Although walking on top of the Caernarfon town walls is no longer possible like in York, it’s still worthwhile to take a leisurely stroll around them. There are grassy areas along the walls that could serve as perfect spots for a picnic.

You can see the windows of St. Mary’s Church which is built into the town walls.

You’ll be amazed at how well-preserved these medieval walls are, stretching for almost half a mile and adorned with eight towers and two gates. They played a crucial role in providing security during the medieval era.

Hole in the Wall street is one of the most charming streets I have ever visiting.

Enter the town through the East Gate and turn left to check out the charming Hole in the Wall Street.  On the western side, the gate was accessible only by sea in the 13th century, giving it the name Water Gate.  Walk along the Quay and you’ll enjoy unobstructed views of the scenic Menai Strait and Anglesey. Towards the northwest corner, you’ll discover St. Mary’s Church, seamlessly integrated into the wall. 

#3 Visit the Segontium Roman Fort

Travel back to Roman times a short uphill walk from the walled town.  Dating back almost 2,000 years, Segontium was a strategically important fort at the edge of the Roman Empire. Established in AD 77 by Agricola, it served as a stronghold for over 300 years.

The Segontium Roman Fort site is huge and impossible to fit in one photo.

Designed to house a regiment of auxiliary infantry, Segontium was connected by Roman roads to major legionary bases at Chester and Caerleon. It played a crucial role in controlling access to fertile Anglesey and defending the Welsh coast against Irish pirates.

Despite the fort’s significant historical importance, its remains were used as a source of stone for the construction of Caernarfon Castle.  Today, you can still see the foundations of many buildings including a shrine, a basilica, and more.

I think there is an exhibition inside this building, but it was locked when I visited.

It is free to visit the Segontium Roman Fort, although the on-site exhibition may have limited opening hours.

Embark on a journey through Snowdonia National Park aboard the Welsh Highland Railway from Caernarfon. This scenic steam train ride unveils picturesque landscapes, showcasing Snowdon’s majestic views and charming villages like Beddgelert, all in a nostalgic atmosphere.
