The excavation at Clachtoll broch has been running for just over a month and with each passing day, the excitement seems to be growing. Clachtoll ticks so many boxes in this aging student’s checklist, it’s hard not to ramble on about it.
Carbon dating tells us that two thousand years ago, someone piled stones forty odd foot high – current estimates from the amount of rubble put the broch at 12-14 metres. I’m far from a pro and not a great judge of distance, so like to describe that as a little higher than a three-storey house. What were they thinking? Was Clachtoll a key location on the West coast in the iron age? Why put what is surely the largest broch on the West coast there?
The excavation is a community run project. After some frankly amazing fundraising, Historic Assynt have raised enough to get in a team of professionals for not just the dig, but a series of workshops, site tours, a little bit of experimental archaeology – next week, a corbelled cell will be built and potentially some local otters may get a new home as an outcome and most importantly it will result in a legacy attraction (complete with new path created from the spoil heap) for future visitors.
Then there’s the manner of the collapse. Most broch’s fell out of use gradually. For one reason or another, their occupants abandoned them, died out or may even have been removed. Many have suffered a gradual collapse over the years – in some cases tens of centuries after their initial construction.
The belief is, that Clachtoll is different. Like many others it collapsed, but in Clachtoll it might have been catastrophic, contemporary, and conclusive enough to prevent re-entry or re-use. Continue reading
