Mighty Caernarfon is possibly the most famous of Wales's castles. Its sheer scale and commanding presence easily set it apart from the rest, and to this day, still trumpet in no uncertain terms the intention of its builder Edward I.

Begun in 1283 as the definitive chapter in his conquest of Wales, Caernarfon was constructed not only as a military stronghold but also as a seat of government and royal palace.

The castle's majestic persona is no architectural accident: it was designed to echo the walls of Constantinople, the imperial power of Rome and the dream castle, 'the fairest that ever man saw', of Welsh myth and legend. After all these years Caernarfon's immense strength remains unchanged.

Standing at the mouth of the Seiont river, the fortress (with its unique polygonal towers, intimidating battlements and colour banded masonry) dominates the walled town also founded by Edward I. Caernarfon's symbolic status was emphasized when Edward made sure that his son, the first English Prince of Wales, was born here in 1284. In 1969, the castle gained worldwide fame as the setting for the Investiture of Prince Charles as Prince of Wales.

History comes alive at Caernarfon in so many ways - along the lofty wall walks, beneath the twin-towered gatehouse and within imaginative exhibitions located within the towers. The castle also houses the Regimental Museum of the Royal Welch Fusiliers, Wales's oldest regiment.

Caernarfon's position of pre-eminence in historic rankings is recognized in its status as a World Heritage inscribed site.
