Early History
Before the grandiose that is the Caernarfon castle was built, the site was at first a Roman fort and then a Norman Bailey and Morte. The latter was incorporated in the stone castle’s design before its destruction in 1870. After King Edward 1 attacked and colonized the Welsh people, he invited James of St. George, a skilled architect, who had traveled widely especially in Constantinople.


The castle was meant to be a royal home and a symbol of strength and dominion of the English people over the local Welsh population. This made the site of ferocious attacks led by Welsh rebels who, while on many occasions failed, once succeeded in capturing the fortress in 1297 under the leadership of Madog ap Llewlyn albeit for a short time.

During construction, workers came from as far as London and supplies and materials were transported to site via sea from Liverpool. This was mainly because Welsh rebels were very effective at ambushing and sacking convoys on land. It is estimated that over a period of 50 years this grand castle cost Edward I about 25,000 pounds in expenditure which was about 90% of his nation’s annual income.
