Caernarfon Castle is possibly the most striking medieval monument in Wales. Its sheer scale and commanding presence set it apart from the rest and, to this day still trumpet in no uncertain terms the intentions of its builder; Edward I. Begun in 1283 as the definitive chapter in his conquest of Wales Caernarfon was constructed not only as military stronghold but also as a seat of government and royal palace. Its unique polygonal towers, intimidating battlements and colour-banded walls were designed to echo 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 undimmed. The castle's symbolic status was emphasized when Edward made sure that his son, the first English Prince of Wales, was born here in1284. 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 in imaginative exhibitions located within the towers. This supreme -and supremely beautiful - fortress is a World Heritage listed site.
