Monument record MHG2517 - Broch, Knock Urray

Knock Urray (Brough) (NR) OS 6"map, Caithness, 2nd ed. (1907)

The ruins of the broch 'Knock Urray', about 54ft in diameter, stand on a grassy mound some 87ft in diameter. The maximum height is about 10ft. Ruins are visible on the E side but no wall-face appears. There are traces of a surrounding ditch.
RCAHMS 1911, visited 1910.

This turf-covered mound, 2.7m high, is generally as described by RCAHMS, but no surrounding ditch is visible. To SE there is a quantity of rubble stones, which is either debris from the mound or a result of stone clearance.
The hillock is conical, and situated on a flat plateau, a position which suggests it is more likely to be a cairn than a broch. No traces of walling could be found.

Knock Urray survives as a turf-covered mound as described by the previous authorities. The 'mound on mound' effect and the former existence of a ditch (RCAHMS) suggest the remains of a broch, but no wall faces are exposed, and there is no central depression. Erosion on NE side reveals a content of earth and small pieces of sandstone. Commonly, when the turf has been removed or eroded from Caithness 'tullochs', a mixture of earth and stones is exposed, at least in the upper layers, but this does not preclude their classification as brochs. According to Mr Gourlay such a content was noticeable in excavated broch at Cross Kirk (ND07SW 4). He noted (i) that the core material between wall faces seemed to be of earth and small stones and (ii) that the large slabs of sandstone readily crumbled to fine chips. Probably for these reasons the sandstone brochs of Caithness tend to be reduced to slumped, ill-defined mounds attracting a turf cover, which contrasts strongly with the brochs further to W which are constructed of harder rock and are more likely to retain their form.
