Càrn Liath is an Iron Age broch on the eastern shore of the Scottish Highlands. The broch has an external diameter of around 19 metres and an internal diameter of around 10 metres. The entrance passage is on the east side and is over 4 metres long. The entrance has elaborate door checks and a bar-hole to control access to the interior. On the right-hand side of the entrance passage is a small guard cell. The surrounding enclosure contains the ruins of additional stone buildings.
The broch was first excavated in the 19th century by the Duke of Sutherland, and was initially thought to be a burial cairn. Finds included pottery, flint chips, stone hammers, mortars and pestles, querns, whorls, shale rings, long-handled bone combs, a whale bone club, a silver fibula, steatite cups and an iron blade.
The site was excavated again in 1986. This showed that the site was occupied in the Bronze Age, before the broch was built. A Bronze Age cist burial with a food vessel was discovered. The foundations of many outbuildings were found in the enclosure surrounding the broch. Although many were clearly from a later period, some may have been contemporary with the broch.
References:The Château de Foix dominates the town of Foix. An important tourist site, it is known as a centre of the Cathars. Built on an older 7th-century fortification, the castle is known from 987. In 1002, it was mentioned in the will of Roger I, Count of Carcassonne, who bequeathed the fortress to his youngest child, Bernard. In effect, the family ruling over the region were installed here which allowed them to control access to the upper Ariège valley and to keep surveillance from this strategic point over the lower land, protected behind impregnable walls.
In 1034, the castle became capital of the County of Foix and played a decisive role in medieval military history. During the two following centuries, the castle was home to Counts with shining personalities who became the soul of the Occitan resistance during the crusade against the Albigensians.
