Architecture and continuing use
The approximately circular interior occupies the summit of a steep rock beside the burn. Surviving evidence includes an inner wall foundation, outer defence and a largely infilled horseshoe-shaped ditch; vegetation and past excavation complicate what can be seen.
Its story
John Smith excavated the site in 1901–1902 and found a levelled clay floor, paving and occupation material, including Roman-period imports and coins. National protection followed in 1969, while modern archaeological sources continue to call the dun interpretation likely rather than absolute.
Why it is included
It extends Dalry’s story far beyond the town streets and provides a well-documented example of archaeological evidence that still requires cautious interpretation.
What to notice
- The steep relationship between summit and Rye Water.
- Traces of wall foundation around the small interior.
- The ditch on the more gently approached side.
Reading the surroundings
No public route has been verified. Do not cross fields or fences, enter woodland without permission, approach the cliff edge, disturb stones or visit during forestry or livestock operations.
