Caernarfon is a royal town, community, and port in Gwynedd, Wales, with a population of 9,615. It lies along the A487 road, on the eastern shore of the Menai Strait, opposite the Isle of Anglesey. The city of Bangor is 8.6mi to the north-east, while Snowdonia fringes Caernarfon to the east and south-east. Carnarvon and Caernarvon are Anglicised spellings that were superseded in 1926 and 1974, respectively. The villages of Bontnewydd and Caeathro are close by.Abundant natural resources in and around the Menai Straits enabled human habitation in prehistoric Britain. The Ordovices, a Celtic tribe, lived in the region during the period known as Roman Britain. The Roman fort Segontium was established around 80 to subjugate the Ordovices during the Roman conquest of Britain. The Romans occupied the region until the end of Roman rule in Britain in 382, after which Caernarfon became part of the Kingdom of Gwynedd. In the late 11th 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 around 1283. Caernarfon is in Gwynedd.
