Why it's Wildland
3.5A low, easily overlooked enclosure on a ridge above Cardiff, where the remains of banks and a ditch hint at a defended prehistoric site.
Graig Llwyn is a modest, weathered earthwork rather than a dramatic ruin. Its appeal lies in reading the faint enclosure on the ridge and considering how the landscape has changed around it; access needs checking before a visit.

The experience
A short, history-led stop if access is confirmed. Take time to distinguish the enclosure’s low earthworks from the surrounding field and consider its position on the ridge.
Things to do
Trace the enclosure in the ground
If access is confirmed, look for the low bank and ditch defining the sub-rectangular enclosure. The site record notes a doubled bank on its eastern side.
15–30 minutes
Notice what time and land use have obscured
A local account describes parts of the earthworks as worn down by farming and one section affected by the lane. The remains may be faint; do not trespass to seek a better view.

Verified history
Coflein records a sub-rectangular defended enclosure on a ridge north of a minor road, measuring about 76 metres east–west by 46 metres. It describes a bank, a ditch and a doubled bank on the east. The record also notes that 19th-century mapping shows a curvilinear feature west of the recorded earthworks. The supplied evidence does not establish a precise construction date or explain the enclosure’s original use.
Hidden details
The doubled eastern bank — Coflein notes that the enclosure’s bank is doubled on the east—a specific feature to look for if the earthworks are visible from a permitted route.
An older mapped feature to the west — The site record says 1875 mapping depicts a curvilinear feature west of the currently recorded earthworks, possibly equivalent to the eastern outworks. This is a recorded interpretation, not a confirmed visible feature on the ground.
