Caernarfon and Conwy are two of Wales's most famous medieval fortresses. Both date back to King Edward I in 1283. While they share a similar history, their designs and visitor experiences differ significantly.
What is the difference in architectural style?
Caernarfon uses polygonal towers, while Conwy uses traditional round towers.
Caernarfon Castle stands out with its distinct polygonal (multi-sided) towers. Its walls feature color-banded masonry modeled on the Walls of Constantinople. Conwy follows a more traditional medieval design with large, rounded towers.
Which castle is larger?
Caernarfon is a gigantic fortress-palace, operating on a larger scale than Conwy.
Caernarfon was designed as the seat of royal power in Wales. It took 47 years and an estimated £25,000 to build. Its defensive network includes nearly 0.5 miles of town walls. Some visitors view Caernarfon as a larger version of Conwy.
What is the visitor experience like at Caernarfon?
Caernarfon offers extensive tower climbs, museum access, and a new lift for limited mobility.
Your £14.90 admission at Caernarfon includes access to the massive Eagle Tower and the Royal Welch Fusiliers Museum inside the Queen's Tower. A newly installed lift in the King's Gate helps visitors access upper levels. Both castles require navigating uneven paths and spiral stairs.
Can I visit both in one day?
You can easily visit both in a single day using guided tours.
If you cannot decide, several tours cover both sites. Tours departing from locations like Liverpool or London offer stops in Conwy to see the historic seaside town before heading to Caernarfon Castle.
How do I choose between Caernarfon and Conwy?
Choose Caernarfon for unique architecture and royal history, or visit both to compare.
If you want to see the birth site of the first English Prince of Wales and unique banded stonework, choose Caernarfon. If you prefer a smaller, traditional coastal fortress, Conwy is a strong option. Many travelers recommend paying to go inside one and viewing the other from the outside.
