Rhosgadfan, Caernarfon, LL54 7HR

Caernarfon, a royal town, community and port in Gwynedd, Wales, has a population of 9,852 when combined with the neighbouring area of Caeathro. The town’s most celebrated landmark is Caernarfon Castle, a medieval fortress that dates back to the late 11th century. The current stone structure, begun by King Edward I in 1283, replaced an earlier motte‑and‑bailey fortification and was built on a grand scale to serve as the administrative centre of north Wales. The castle’s walls echo the Walls of Constantinople and reflect a deliberate link to Caernarfon’s Roman past, with the nearby Roman fort of Segontium. The historic setting gives the town a distinctive character, and its status as a port adds to its cultural significance. The combination of medieval heritage and Roman history makes Caernarfon a unique place to live or visit within Gwynedd.
