of the Orkney Archaeological Trust
are an active group who are keen
to explore the numerous archaeological monuments on the islands.
Orkney is blessed with having a wide range of archaeological sites,
but many of these are under threat from coastal erosion. Sites from
all periods are in danger, from prehistoric habitation sites to Second
World War defences.
The group are monitoring
a few sites, and one of the more spectacular is a probable broch
on the east coast of Mainland. This structure is over two metres
high and several cells can be seen in the eroding cliff edge.
As well as structural elements, the sea is washing away evidence
of the diet of the former inhabitants. Middens, or dumps of rubbish,
made up of sea shells and animal bone are visible in many places
along the section. The group is continuing to monitor the site
and plans to make a detailed photographic record of the structure
to compare with similar photos taken a few years ago.
