Caernarfon is a royal town, community, and port in Gwynedd, Wales, with a population of about 10,000. It is along the A487 road, around the eastern shore of the Menai Strait, opposite the Isle of Anglesey. Bangor is 8.6 miles (13.8 km) to the north east, whilst Snowdonia borders Caernarfon to the east and south-east. Carnarvon and Caernarvon are Anglicised versions of the name that were superseded in 1926 and 1974, respectively. The villages of Bontnewydd and Caeathro are nearby. Rich natural resources around the Menai Straits enabled humans to live in prehistoric Britain. The Ordovices, a Celtic tribe, lived in the area through the period known as Roman Britain. The Roman fort Segontium was established around AD 80 to subjugate the Ordovices throughout the Roman conquest of Britain. The Romans occupied the region until Roman rule ended in Britain in 382, and Caernarfon became part of the Kingdom of Gwynedd. In the late eleventh century, William the Conqueror ordered the construction of a motte-and-bailey castle at Caernarfon as part of the Norman invasion of Wales. He was unsuccessful, and Wales remained independent until about 1283. During the 13th century, Llywelyn ap Gruffudd, ruler of Gwynedd, refused to pay homage to Edward I of England, which led to the English conquest of Gwynedd. This was followed by the building of Caernarfon Castle, one of the largest and most imposing fortifications built by the English in Wales. The city has turned into an important tourist centre and seat of Gwynedd Council, with a bustling harbour and marina. Caernarfon has expanded beyond its medieval walls and experienced heavy suburbanisation. Its population consists of the biggest percentage of Welsh-speaking citizens anywhere in Wales. The castle and town walls are part of a World Heritage Site described as the Castles and Town Walls of King Edward in Gwynedd.
