The town of Caernarfon in Gwynedd, Wales sits at the mouth of the River Seiont, looking across the Menai Strait towards Anglesey. Its dramatic medieval defences and Caernarfon Castle, built by Edward I as part of his conquest of the region, dominate the waterfront and remain one of the area’s principal heritage attractions, famously hosting a 20th‑century investiture of the Prince of Wales.
Caernarfon retains a strong Welsh‑speaking community and a lively cultural life, with markets, festivals and music reflecting local traditions. Historically tied to the nearby slate quarries around Dinorwic and Llanberis, the town today relies on tourism, harbour activity and local services, with the scenic heritage railway link to Porthmadog adding to its appeal.
