Report Summary

Non-invasive fieldwork carried out on the Neolithic long barrow at Capo, present-day Aberdeenshire (NGR NO 633 664) has considerably enhanced our knowledge of this monument. Topographical survey has provided the first detailed record of the barrow and its environs. Resistivity imaging has revealed key elements of the structure of the long barrow, including side revetment walls, a  flat façade and possible mortuary structures, confirming that the barrow at Capo is of a similar morphology to the nearby (excavated) long barrow at Dalladies. The resistivity survey has demonstrated that rabbit burrowing and the roots of the tree stumps that covered the barrow have had little effect on the integrity of the major structural elements of the monument (the revetments and façade). However, it is not possible to assess the more subtle damage, such as mixing of archaeological layers, which may have been caused. It is concluded that, whilst resistivity imaging at the survey density employed here is time-consuming and would not be appropriate at many sites, as a management tool and as a means to explore sites that are unavailable for excavation, such as scheduled ancient monuments, it has been demonstrated to be of considerable value.
