Dyffryn Ardudwy is in the northwest of Wales in the region Gwynedd, 40 m above sea level on the flat slope of Moelfre in an enclosed by a wall and a woodland area at the edge of the village, which gave it its name.

The excavation in 1960 revealed a well-preserved two-phase built monument. First, a small chamber was built, which was in an oval cairn or a low platform with an atrium. The small chamber consists of six supporting stones supporting a capstone. Before the portal, the parts of several Neolithic vessels, the type of fine simple " Irish Sea goods " were found in a pit.

Later, a second chamber was built east of the first. This chamber has now also a modern concrete pillar to support the larger capstone. The chamber had a porch, which zerscherbte pottery contained. Neolithic and Bronze Age pottery was also found inside the chamber. Some of the vessels contained dark earth with a concentration eingeäscherter bones that belonged to a single individual. Seven flints were found between the stones of Cairns and a broken arrowhead was at its eastern end.

Both chambers of Dyffryn Ardudwy were ultimately integrated into the common stretched very flat Cairn and enclosed by a low platform. But it is possible to detect the shape and the size of the original smaller oval Cairns, which was initially established by Western chamber.
