The construction, use and re-use of Bargrennan chambered cairns, Galloway (2002-6)

There are two different types of chambered cairn in Galloway – long rectangular cairns and circular cairns with narrow passages leading to the chambers. While four long cairns have been excavated, prior to this project only one of the round ‘Bargrennan’ sites had been partially investigated, during three days in 1949.

During this project we excavated two Bargrennan sites: Cairnderry, a Bargrennan monument with three chambers, and the single-chambered site of Bargrennan White Cairn.

The aims of the project were to:


Cairnderry had been severely robbed in the past, and no deposits were found to survive in the southern chamber. However, we did find an early Neolithic flint and pot assemblage underneath the cairn at Cairnderry. We identified that the monument was originally hemmed by a kerb of flat-faced stones.

In 2003 we also found five early Bronze Age cremation pits around the kerb to the south-east of the monument. These pits all contained cremated bone – some of which we have had radiocarbon dated - and charcoal.

One pit also contained some spectacular grave goods: an early Bronze Age battleaxe, an upturned collared urn and an accessory vessel. This evidence suggests that c.1900-1700 BC people were using the outside of the monument for funerary activities.


Bargrennan was examined through trenches into and in front of the passage, and in 2005 also at the rear of the site. We identified that the cairn here was also bounded by a kerb (both at front and back of the site), and appears to have been built in a single event.

Early Bronze Age mortuary activity was discovered, including a cist inserting into the cairn and containing an urn holding cremated human remains, and three other features containing cremated human bone. One of these contained an inverted collared urn in which were cremated bones, a bone pin, and pieces of a stone battleaxe which was fractured by heat.

We have now analysed and compared the findings from both sites. We also considered the findings in the context of local Neolithic and early Bronze Age activity, including comparison with the evidence for the early Bronze Age re-use of Clyde monuments known from earlier excavations.
