The name Dwygyfylchi is Welsh for "the meeting of two semicircles", in reference to the nearby promontories of Penmaenbach and Penmaenmawr. The origin of the name Capelulo, the original settlement, lies in its association with Saint Ulo.
Geography
Approximately half of Dwygyfylchi forms the most northern tip of the Snowdonia National Park. Half a mile to the south-east of the main village lies Capelulo, which lies at the foot of the picturesque Sychnant Pass, which connects Dwygyfylchi to Conwy. The Pensychnant Conservation Centre and Nature Reserve is nearby. Two headlands separate Dwygyfylchi & Penmaenmawr from its neighbours. Towards the east Penmaenbach divides Dwygyfylchi from the neighbouring town of Conwy Morfa and the Conwy Valley leading up to Betws-y-Coed. To the west the larger headland of Penmaenmawr divides them from the town of Llanfairfechan and the wider coastal plain extending to Bangor. To the south an arc of hills and uplands extends east to west from the latter to Penmaen Mawr, beginning with Yr Allt Wen above Dwygyfylchi, Bwlch Sychnant and Pen-sychnant at Capelulo. The rounded hill of Foel Lys, Gwddw Glas, Bryn Derwydd and the head of Cwm Graiglwyd and finally Penmaenmawr itself. The coastal plain itself is nearly divided by Trwyn-yr-Wylfa, which also marks the boundary between the "Hen Bentra" or "Old Village" of Dwygyfylchi and Capelulo in the east and Pant-yr-afon and Penmaenan in the west. Finally two small rivers flow through the area. The first and larger, Afon Gyrrach, runs for about 4 miles from the northern slopes of Tal-y-Fan to the sea near Penmaenbach, passing through Nant Ddaear-y-llwynog and the old villages of Dwygyfylchi and Capelulo. The second, Afon Pabwyr, runs down from wooded Cwm Graiglwyd then under the town centre, Pant-yr-afon, to the beach.
History
The surrounding landscape is dotted with palaeolithic, mesolithic, neolithic, Bronze Age and Iron Age structures, including cromlechs, standing stones, stone circles and hill forts. Notable Iron Age hill forts in the area are Caer Seion, at the summit of Conwy mountain, and nearby Braich-y-Dinas, one of the largest Iron Age hill-forts in Europe, at the summit of Penmaenmawr. Nothing remains of Braich-y-Dinas, however, as the last remnants were destroyed in the 1920s. The 1868 National Gazetteer of Great Britain and Ireland notes: "In this neighbourhood are a great number of antiquities, consisting of cromlechs and single upright stones, the remains of a British camp, with ditches and ramparts, &c." About a mile or so north of Dwygyfylchi & Penmaenmawr lies Llys Helig. This has been said to have been the palace of Prince Helig ap Glanawg or Glannog who lived in the 6th century Prince Helig ap Glanawg owned a large area of land between the Great Orme's Head near Llandudno and the Menai Strait off the north coast of Gwynedd. This area was inundated by the sea which has given rise to the legend of the drowned kingdom. The legend states the remains of Llys Helig, said to be his palace, can be seen at exceptionally low tides, this being near the Conwy channel, about a mile or so off the coast at Penmaenmawr. The earliest known use of the name Llys Helig regarding this rock formation is the Halliwell Manuscript which is believed to date to around the beginning of the 15th century, nine centuries later. The Llys Helig rock formation is a glacial moraine left behind by previous subsequent ice ages. There is a fish weir south of this which tradition dates to the beginning of the 6th century which was used up until the early 20th century. The sea level was low enough around 1600 AD to make the claims of Sir John Wynne of Gwydir feasible. The Church in Walesparish church, dedicated to SaintGwynin or Gwynan, was built between 1888 and 1889. The pews of the present church were made from the roof timbers of the earlier church building constructed in 1760, the foundation stone of which was preserved and mounted on the vestry wall of the present church, where it can still be seen. St Gwynin's gwyl mabsant is December 31. Dwygyfylchi is also associated with Saint Ulo, Capelulo at the foot of Sychnant reputedly having been the site of an early medieval church. In 1851, in addition to the parish church, with a congregation of 80 and 20 scholars, the village had also a Wesleyan Methodist chapel at Penmaenmawr, a Welsh Calvinistic Methodist one at Pen y cae Chappel, and a Horeb Nonconformist chapel.
