Craggan Crannog is located on the south shore of Loch Tay near the Boy’s Brigade Centre. It is just west of Dall Bay [about 1km], and so potential contemporaneity between Craggan and either of the Dall Bay crannogs would be very exciting and suggest that there was a relatively thriving community in the are if it could support the building and maintenance of two of these large, perhaps ostentatious, structures.

Craggan Crannog timbers just under the boulder capping of the crannog.
Preservation of the timbers, even in very shallow water, was excellent.

Earlier dating on Craggan had suggested there were both Early Iron Age and Early Medieval phases on the site. The site is a little unusual in being more lozenge shaped than circular, and it is located in relatively shallow water, only 20 m from the shore at it nearest point. Earlier survey work in the early 2000s, had suggested the only visible timbers were located on top of the crannog mound, and that is where we targeted our single trench on this site in August 2018. That work turned up lots of timbers in a very short period of time, most poking through organic debris layers and the upper boulder capping of the crannog. The timbers were sampled, and have now been individually radiocarbon dated with exciting results.

The new rangefinders show that all the timbers we sampled are Early Iron Age in date, and unusually, seem to all sit on the earlier part of the Hallstatt Plateau. The degree to which this is apparent, rather than a real reflection of the true felling date of the timber, our forthcoming wiggle-match dates will hopefully sort out. If actual felling date for these timbers sits before c. 500 cal BC, these will be some of the earliest dates for Iron Age crannog building activity in Loch Tay and indeed the rest of Scotland. These dates could all be contemporary with Dall Bay South crannog, and indeed Oakbank and Milton Morenish which were all investigated in 2017.
