Caernarfon

Caernarfon is a royal town, community, and port in Gwynedd, Wales, with a population of around 9,615. It is positioned on the A487 road, on the eastern shore of the Menai Strait, opposite the Isle of Anglesey. The city of Bangor is 8.6 miles (13.8 km) to the north east, while Snowdonia borders Caernarfon to the east and south-east. Carnarvon and Caernarvon are Anglicised versions of the name that became old fashioned in 1926 and 1974, respectively. The villages of Bontnewydd and Caeathro are nearby. Abundant natural resources close to the Menai Straits allowed human habitation in prehistoric Britain. The Ordovices, a Celtic tribe, lived in the region throughout the period generally known as Roman Britain. The Roman fort Segontium was established around AD 80 to subjugate the Ordovices during the Roman conquest of Britain. The Romans occupied the region till Roman rule ended in Britain in 382, after which Caernarfon became part of the Kingdom of Gwynedd. During 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 until around 1283. In 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 construction of Caernarfon Castle, one of the biggest and most imposing fortifications constructed by the English in Wales. The city has developed into an important tourist centre and seat of Gwynedd Council, with a busy 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. For all your home upgrades, make sure that you work with reliable experts in Caernarfon to ensure you get a good quality service at a great price.
