Archaeology Notes

(ND 0489 6345) Mound (NR)

OS 6" map, Caithness, 2nd ed., (1907)

That this is a broch is suggested by the character and curve of the wall of the small fragment of building here.

RCAHMS 1911.

This is a grass-covered mound, 1.2m high, 14.0m E-W by 10.0m transversely, with asmall pile of grass-covered stones on the top. Though artificial, there is now no evidence to suggest that this is a broch; nor could its nature be determined.

Resurveyed at 1:2500.

Visited by OS (R D) 22 October 1964.

No change to the previous field report.

Visited by OS (J B) 5 October 1981.
