Dun Colbost revisisted


Broch entrance and outer wall
Plan by Swanson

Directions and Access:
NG 2055 4947

The broch is situated on Colbost Common Grazings, on a rocky knoll above the Dunvegan to Glendale Road.

There is room to park a  car  at a small quarry (approximate grid reference NG 2023 4964) or at the layby opposite Skye Silver.  A track leads up the hill from the quarry.  As the track ends, the broch comes into view and is reached by crossing boggy moorland. Approximately 10 minutes walk.

The Broch


In the original RCAHMS description of Dun Colbost (1904) no entrance was visible but they believed “it was probably in the west”.  The broch was described as being in “poor condition”.  Nevertheless, subsequent excavations have revealed tantalising but inconclusive information hinting at a more sophisticated structure.  Glendale Trust  is currently investigating the possibility of obtaining funding for a more in depth excavation.

An excavation, carried out in 1989, exposed the entrance to the broch as well as interesting evidence of a cobbled area outside the broch.    

 



The entrance itself is obscured by a "danger" sign

Further excavation in 1990 added little knowledge but in 1994, the area between the broch wall and the outer “perimeter “ wall revealed evidence of stone paving, covered drains, and a hearth.  

 Curiously there seems to be no entrance in the outer wall which corresponds to the broch entrance.



There is a terrace south of the entrance which is mentioned in the brief description of 1990 excavation but no suggestion is offered as to its purpose.  In a modern house, it would make a lovely flower bed!






Possibly  lintel over intra mural gallery in East


The inside of the broch is full of tumbled stones and it is difficult to see much evidence of the mural gallery mentioned on canmore and no scarcement can be seen.





There appears to be a very small structure inside the broch  just north of the entrance – perhaps a sheiling or bothy created after the broch had been destroyed.   


Internal structures north of entrance


circular hole crossed with lines



One of the stones in the North West Sector  has an intriguing circular hole about 3" deep - it looks too perfectly circular to be natural.







An enclosure/sheep fank to the east of the broch has clearly made use of many of the stones.  This enclosure is shown on the 1877 map of the area.
