Geography
The village of Dyffryn Ardudwy is situated on the A496 coastal road between the towns of Harlech and Barmouth and at the foot of Moelfre, part of the Rhinogydd range. The village has a railway station and a long sandy beach backed by sand dunes. A small river, Afon Ysgethin, flows through the area of the community, crossed by two very old bridges: Pont Scethin and Pont Fadog.

History
There are a number of prehistoric cromlechs in and around the village, and they are some of the earliest tombs erected on these islands. Dating from around 4000 BC, the cairn at Dyffryn Ardudwy has two separate burial chambers. One of these is a type known as a portal dolmen. A flat slab on the mountainside was used as a base, this was flanked by several other slabs, side-stones and back-stones. A capstone was placed on top and a small ovoid cairn of stones built around three sides. The fourth side was the portal and had a small forecourt. Here a pit was dug and in it were formally arranged several flat stones, various shards of pottery from at least four pots, charcoal and soil. The pit was then filled with the cairn material and the mound completed.

Near Dyffryn Ardudwy is an avenue which was built by the powerful Vaughan dynasty, (who were instrumental in placing Henry VII of England on the throne in 1485), to connect their family mansion, Cors-y-gedol (The Bog of Hospitality), with the family chapel. The existing mansion was built in 1576. It is Grade II* listed house, set in parkland which is designated Grade II on the Cadw/ICOMOS Register of Parks and Gardens of Special Historic Interest in Wales. Nearby, the Cors-y-gedol burial chamber stands amidst the site of ancient fields and settlements and the area affords glorious views of Cardigan Bay.

St Dwywe's Church at Llanddwywe, within the community of Dyffryn Ardudwy, was built on an ancient mound which is at the end of the straight line followed by the road to Cors-y-gedol Hall. This line runs straight and true to a cairn on the side of Moelfre, and it is suggested that this is a prehistoric man-made creation relating to the summer solstice rather than a more recent addition. The church is a Grade II listed building.
