Caernarfon Castle: Edward I’s Most Emphatic Statement in Stone

The banded stonework on Caernarfon Castle’s towers was copied directly from the Byzantine city walls of Constantinople, a deliberate visual reference that Edward I expected the educated observers of 1283 to recognise. By invoking Constantinople’s imperial authority in stone, he was claiming that his conquest of Wales had the same permanence and legitimacy as the Byzantine Empire. It was sophisticated propaganda in a pre-print era, communicated entirely through architecture.

Caernarfon Castle was not built as a functional fortress first. It was built as a statement. When Edward I finished his conquest of Wales in 1283, he didn’t build a straightforward defensive structure - he built something designed to intimidate and overawe. The octagonal towers, the banded stonework copied from the Byzantine city walls of Constantinople, the strategic position at the mouth of the Seiont River where it meets the Menai Strait: every detail was calculated to signal permanent occupation.

The castle was designated a UNESCO World Heritage Site in 1986 alongside Conwy, Harlech, and Beaumaris as part of the Gwynedd castles grouping. Of the four, Caernarfon is the most dramatic and the most intact.

What to See Inside

The Eagle Tower at the castle’s western end is the most recognisable section: three turrets topped with carved stone eagles, built as the private quarters of Edward’s representative in Wales. The views from the top take in the Menai Strait, Anglesey to the north, and the Snowdonia mountain range to the east. On a clear day this is one of the best natural panoramas in Wales. The climb involves a narrow spiral staircase - not suitable for those with mobility difficulties.

The Queen’s Tower houses the Regimental Museum of the Royal Welch Fusiliers, covering the regiment’s history from the late 17th century through to recent conflicts. It is a proper regimental museum with serious artefacts, not a theme park exhibition. Allow 30-45 minutes.

The North Hall and surrounding interior has been well-preserved and gives a strong sense of the castle’s 13th-century scale. Audio guides are available (included in the admission price) and are worth using.

Investiture exhibitions: Prince Charles was invested as Prince of Wales at Caernarfon in 1969. There is permanent material relating to this event, including film footage. This is either interesting or irrelevant depending on your view of the monarchy.

Admission prices: Adults £12.50, concessions £10.50, children (5-15) £8.50. Open April-October 09:30-17:00, November-March 10:00-16:00.

Caernarfon Town

The castle dominates the town, which is small, Welsh-speaking, and less touristic than its famous tenant might suggest. The old walled town (partially surviving) is worth walking around. The town square (Y Maes) has the standard market town layout, with a statue of Lloyd George - the most famous politician to come from this area - at one end.

Galeri Caernarfon on Victoria Dock is an arts centre worth noting: cinema, gallery, and cafe with a good view of the Menai Strait. It programmes Welsh-language and English events and is actively used by locals.

The Royal Town of Caernarfon is compact enough to see on foot in a morning. The afternoon is better spent at the castle itself or on a boat trip on the strait.

Eating

Cegin Fach (Pool Street): good Welsh breakfast, reliable lunch menu, locally run. Coffee is better here than at the castle’s own facilities.

The Anglesey Arms (Harlech Road): traditional pub, decent bar food, views of the castle walls from some seats. The real ales are local.

Stones Bistro (Hole in the Wall Street): evening restaurant, Welsh produce, good for a proper meal if you’re staying overnight. Booking ahead at weekends is advisable.

For a quick bite near the castle, the café at Galeri is better value and quality than most of the tourist-facing options immediately adjacent to the castle walls.

Getting There

Caernarfon is 9 miles south-west of Bangor. By car on the A487, the journey takes about 20 minutes from Bangor. Bangor has a railway station on the North Wales main line from Chester and Crewe.

From Bangor station: bus S4 runs regularly to Caernarfon (around 40 minutes, Arriva Buses Wales). There is no railway station in Caernarfon itself.

By car from Cardiff: 3.5-4 hours on the A470 and A55. Parking in Caernarfon town centre is paid; there are larger car parks near the castle that fill quickly on summer weekends.

Where to Stay

The Black Boy Inn (Church Street): 16th-century coaching inn, 22 rooms, characterful without being precious about it. Breakfast included, around £80-100 per night. Five minutes’ walk from the castle.

Celtic Royal Hotel (Bangor Street): larger and more corporate, useful if you need reliable facilities, less interesting as an experience.

For Snowdonia access, consider staying in Llanberis (7 miles east) and doing the castle as a half-day trip. Llanberis has better walking base options.

Practical Notes

The castle walls walk is separate from the main castle interior and involves some exposed sections without handrails at height. Wear decent shoes. The paths are stone and uneven.

Welsh weather is genuinely unpredictable year-round. A waterproof layer is the most useful single item you can bring, even in July. The castle provides no meaningful shelter from horizontal rain.

Caernarfon gets very busy in July and August. Visiting on a weekday morning in May, June, or September gives you the castle largely to yourself and makes the Eagle Tower worthwhile rather than a queue exercise.
