Llwynda-Ddu Camp

Llwynda-Ddu Camp, also known as Llwynda-Ddu Hillfort, is a small Iron Age earthwork in Pentyrch, Cardiff in South Wales. The site is a scheduled monument, described as a prehistoric, defensive hillfort.

The plan of the camp is egg-shaped and lies at the western end of a small hill at a height of approximately 120 m. The ground falls away sharply on all sides except the eastern end. The entrance is at the smaller south-western end.

The camp probably comprised two ramparts with ditches but much of the outer ring has been destroyed. The entrance is a straight causeway which interrupts the inner and outer rings. The height of the bank is approximately 2.5 m higher than the ditch bottom. The inner area measures 85 m by 60 m giving an area of 0.4 ha.

The site has been cultivated, with a modern dwelling nearby. It is suggested that the camp belonged to the Silures.
