Caernarfon
Caernarfon is a royal town, community, and port in Gwynedd, Wales, with a population of approximately 10,000. It is located on 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 Carnarvon and Caernarvon are English versions of the name that were superseded in 1926 and 1974, respectively. The villages of Bontnewydd and Caeathro are nearby. Abundant natural resources in and around the Menai Straits allowed humans to live in prehistoric Britain. The Ordovices, a Celtic tribe, lived in the region during the period called Roman Britain. The Roman fort Segontium was established about AD 80 to subjugate the Ordovices throughout the Roman conquest of Britain. The Romans occupied the area till the end of Roman rule in Britain in 382, after which Caernarfon became a part of the Kingdom of Gwynedd. In the late 11th century, William the Conqueror ordered the building of a motte-and-bailey castle at Caernarfon as part of the Norman invasion of Wales. He was unsuccessful, and Wales remained independent till about 1283. In the thirteenth 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 construction of Caernarfon Castle, one of the biggest and most imposing fortifications constructed by the English in Wales. The city has come to be a major 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 includes the largest percentage of Welsh-speaking citizens anywhere in Wales. The castle and town walls are a part of a World Heritage Site described as the Castles and Town Walls of King Edward in Gwynedd.
