Crannogs and artificial islets are distributed across Scotland where conditions are suitable, with late Bronze Age to early Iron Age dates for the earliest recognisable timber crannogs and artificial islets constructed on a large scale during the period circa 800-500 BC, which has been termed the ‘crannog event horizon‘ by Cavers (2006). Crone notes that currently known distributions may reflect research bias, except for the situation in South East Scotland where there appears to be a genuine dearth of crannogs, probably largely due to the relative scarcity in this region of suitable locations (2000).
That said, there are five possible crannogs within the area. One in Edinburgh at Duddingston Loch, also the site of a Bronze Age votive deposit, which was discovered in the mid-19th century but is no longer visible. It was described as a collection of timber piles or stakes at regular intervals, firmly imbedded into the lake bed and located close to the shore (Stuart 1868). A further four possible crannogs are listed within the Scottish Borders in the Trove database. Perhaps the most compelling of these is one that was noticed via aerial photography in 2007 in Hoselaw Loch in Linton, Scottish Borders. The possible crannog is noted as being an island in the south east of the loch with an indication of a sub-circular structure.
