Architecture, archaeology and continuing use
A buried ditch between two and three metres wide encloses a roughly circular area 33 metres across. A conspicuous 6.6-metre entrance opens on the west, while deep colluvial soil may conceal structures not visible from the air.
Its story
Aerial photographs taken in 1977 recorded the enclosure after drought conditions. Comparison with the similar Drumcross site suggests a domestic or agricultural enclosure, but its interior has not been excavated.
Why it is included
Scheduling protects a scarce west-central lowland enclosure whose buried soils and ditch fills may retain buildings, artefacts and organic evidence.
What to notice
- Circular cropmark rather than masonry.
- Wide western break marking the entrance.
- Relationship with the nearby Drumcross enclosure.
Reading the surroundings
Do not enter the working fields without permission or disturb soil. Cropmarks may be invisible from ground level, and lawful public observation should never involve drones, detecting or collection without consent.
Timeline
- Later prehistory The circular enclosure was probably created for domestic or stock-related use.
- 1976 Drought conditions increased the later visibility of buried features.
- 1977 Aerial survey photographed the ditch and entrance.
- 2011 National scheduling protected the surviving deposits.
What we know — and what remains uncertain
The date and function remain interpretations based on cropmark form because no excavation is recorded.
