Architecture, archaeology and continuing use

The sub-circular enclosure measures roughly fifty to sixty metres across. Steep slopes defend most approaches, while a rampart about 1.5 metres high and a ditch strengthen the easier eastern side. An outer rampart is now faint.

Its story

Iron Age communities selected the spur for defence and settlement. Later ploughing improved the pasture and reduced some outer earthworks, but the main rampart, ditch and buried interior survived. A 120-metre protected area was scheduled in 1988.

Why it is included

The fort is nationally important as an unusually well-surviving lowland earthwork with potential to reveal Iron Age domestic life and defensive planning.

What to notice

  • The strongest rampart on the approachable side.
  • The ditch cutting off the spur.
  • The apparently empty interior where buried remains may survive.

Reading the surroundings

Do not cross private pasture without permission. Observe livestock precautions, avoid erosion on ramparts and never dig, detect or disturb the scheduled area.

Timeline

  1. Iron Age A community enclosed the spur with ramparts and a ditch.
  2. Later centuries Ploughing softened parts of the outer defences.
  3. 1988 Scheduling protected the surviving earthwork and buried interior.

What we know — and what remains uncertain

No excavation date is available for construction or abandonment, and field visibility varies with vegetation and grazing.
