Caernarfon Castle: What Edward I Actually Built Here

Edward I did not build Caernarfon Castle to be admired. He built it to subjugate a country. Construction began in 1283 in the wake of the conquest of Wales, and the design, with its polygonal towers, banded masonry, and eagle battlements, was deliberately modelled on the walls of Constantinople. The symbolism was pointed: this was a statement that Wales had been absorbed into an empire with ambitions reaching back to Rome. Walking the walls with that context in mind changes what you are looking at.

The castle is managed by Cadw, the Welsh government’s historic environment service. Adult admission is £15.20 in peak season (June to August), dropping to £14.50 from September to March. The castle opens from 09:30 to 17:00 in spring and autumn, 09:30 to 18:00 in summer, and 10:00 to 16:00 from November to February. Guided walking tours lasting 45 minutes run at 11am and 3pm daily for an additional £5 per person; these are worth taking for the interior narrative, which the self-guided material does not fully supply.

Inside the Castle

The Eagle Tower, the largest of the castle’s towers, is the one to prioritise. It stands at the western end of the enceinte and was originally the residence of the first English-born Prince of Wales, later Edward II. The tower’s three turrets, each topped with stone eagles, would have been visible from the Menai Strait to anyone approaching by sea. From the top, the views over the strait toward Anglesey are as instructive now as they were strategically: this position controlled the sea crossing, the river mouth, and the roads into Gwynedd.

The Royal Welch Fusiliers Museum occupies the Queen’s Tower and is included in the castle admission. It is a surprisingly good regimental museum covering the regiment’s history from the 17th century through recent conflicts. Worth an hour if military history interests you at all.

The Town Walls

The medieval town walls that connected the castle to the town are largely intact and walkable. Following them gives a complete sense of Edward’s original garrison town design: a walled settlement inside which the English settlers could live, with the Welsh confined to the surrounding countryside. The walls take about 30 minutes to walk and are free once you are inside the castle. Most visitors skip them; that is a reasonable choice if time is short but a loss architecturally.

Where to Eat

The Galeri arts centre café on the waterfront is the best option in town: a bright, well-run space with locally sourced food, good coffee, and views of the castle walls. The White Harp on the Maes offers solid Welsh pub fare in a building that has been feeding people near this spot for centuries. For a proper sit-down dinner, the restaurants along Pool Street are the practical choice.

Avoid the tourist traps immediately adjacent to the castle’s main gate; they have the worst food and the highest prices, as is traditional.

Where to Stay

Castle Hotel Caernarfon is the obvious choice if you want castle views from your room; it is comfortable, well-run, and genuinely positioned on the town square with sightlines to the walls. The Victoria Hotel is serviceable and cheaper if the location premium is not a priority for you.

Beyond the Castle

Segontium Roman Fort on the eastern edge of town is one of the better-preserved Roman military sites in Wales, garrisoned from approximately 77 to 390 AD. The small museum on-site explains its strategic role in the Roman occupation of Britain. Most Caernarfon visitors never find it; that means it is quiet, which is its own reward.

Snowdonia National Park begins immediately to the east. The Llanberis path up Snowdon starts about 10 km from Caernarfon; the Snowdon Mountain Railway from Llanberis is the alternative for those who prefer their mountains from a seat. Portmeirion, the eccentric Italianate village designed by Clough Williams-Ellis and filmed as the location for the 1960s series The Prisoner, is about 30 km south along the coast.

Getting There

Caernarfon is 9 km southwest of Bangor, which has the nearest train station on the North Wales Coast Line from Chester and Holyhead. Buses run between Bangor and Caernarfon regularly; the journey takes around 30 minutes. By car from Chester the drive is about 1.5 hours; from Cardiff, around 4 hours.
