Discovery of island ritual site where people gathered 5,000 years ago
The spectacular feature in the landscape is likely to have drawn people from all over a Scottish island around 5,000 years ago for ritual and ceremony.
The discovery of a cursus monument site at Tormore on the Isle of Arran, which is more than a kilometre long, is helping to reshape Neolithic history in Scotland with such landmarks usually associated with the east coast.
Cursus monuments were often defined by long lines of timber posts, forming a long rectangle, and were amongst the most spectacular features in the Neolithic landscape.
The posts may have served as a procession route, perhaps to honour the dead. Some were burned to the ground in an almighty display which is believed to have been part of the ceremonies associated with these huge monuments.
Dave Cowley, Rapid Archaeological Mapping Programme Manager at Historic Environment Scotland, who discovered the site following a laser scan of Arran, described the cursus monument as a “cathedral of the day”.
He said: "I think if you asked the survey team what they thought they were most likely to find on Arran, I would bet you no one would say a Neolithic cursus monument.
“There is no other on Arran, it’s unique on the island, there is one more in Kilmartin Glen and that is pretty much it for the western seaboard.
“What this example at Tormore tells is there are probably actually many more on them but because they were built from timber, you are not likely to see them in the unimproved peat landscape of the west coast.”
Mr Cowley detected the site after picking up two lines of mounds, which lie roughly parallel and stand 30 to 40 centimetres high, and which run for around a kilometre.
Mr Cowley said the monuments probably brought together “quite dispersed populations together in a communal activity” and that different
communities built different parts of the monument.
The site was discovered following an aerial laser scan of the site using Light Detection
and Ranging (Lidar) technology, which uses laser pulses to measure objects. Images can then be reworked by filtering out vegetation which
can then reveal previously unknown characteristics in the land.
