Chwilog (Welsh pronunciation: [ˈχwiːlɔɡ]) is a village in Gwynedd, north Wales, and located on the Llŷn Peninsula. It is in the community of Llanystumdwy, near Criccieth, and in the medieval commote (Welsh: cwmwd) of Eifionydd, named after a 5th-century ruler. It is within the Dwyfor Meirionnydd constituency in the UK Parliament and in the Senedd (Welsh Parliament). The name means 'abounding in beetles' and was perhaps transferred from an earlier name of the river (or a part of it).^[1][2][3]

It had a population of 640 in 311 households as of the 2011 UK census, with 78% born in Wales.^[4] In the 2021 census of the UK, the Llanustumdwy community with a 60km sq radius, which includes Chwilog had a population of 1917 inhabitants.^[5]

Village

The village is fairly linear, built up around the B4354 which used to be a turnpike/toll road crossing the peninsula to Porthdinllaen. The Afon Wen or its original name Afon Carrog flows through the lower part of the village on its way to the sea at Afonwen, less than 1 mile (1.6 km) away.^[6]

Y Lôn Goed

Nearby is Y Lôn Goed (English: Tree Lane) is a 7-mile tree-lined path. It was first nicknamed by the local population. It is a wide tree-lined avenue created in the 18th century for transporting lime, coal, and peat from the coast to the upland farms of Eifionydd, including Plas Hen locally. The track is no longer used for this purpose but is now popular with walkers.^[7][8][9]

Local halls (Plas)

During the 16th century, a residence named Plas Chwilog was established in the vicinity. The family was descendants of Rhodri, son of King Owain Gwynedd (c. 12th century), and also the Powys Fadog dynasty (12th–15th centuries). The patriarch of Chwilog, Griffith Llwyd (Lloyd) was the son of Morris of Clenennau, Dolbenmaen. He founded the hall (plas) near the village of Llanystumdwy. A son of Llwyd married a descendant of Hywel Coetmor, he had sided with Prince Owain Glyndŵr during the early 1400's Welsh rebellion.^[10][11]

Near Chwilog is Talhenbont hall, a manor house (plas) built in 1607, it is now a Grade II listed building. The property, formerly named Plas Hen, was inherited in 1870 by the future Baronet Hugh Ellis-Nanney of Gwynfryn and Cefndeuddwr. He became the owner of a 12,000 acre estate in North Wales surrounding Chwilog. As well as the Talhenbont residence, he owned the homes near Criccieth. Ellis-Nanney also inherited Bryn Hir and rebuilt the mansion Plas Gwynfryn before 1876.^{[12][13][14][15]}
