Culswick Broch is an unexcavated coastal broch, an Iron Age drystone hollow-walled structure. Built of striking red stone, it has beautiful views all around, including Foula and Vaila isles, and Fitful Head and Fair Isle in the south. The broch stands commandingly on the top of a massive rock platform and is about 3 metres high at its tallest point. Much rubble has fallen into the centre. This broch has a massive triangular lintel stone over the entrance, which is partly filled with rubble.
References:Doune Castle was originally built in the thirteenth century, then probably damaged in the Scottish Wars of Independence, before being rebuilt in its present form in the late 14th century by Robert Stewart, Duke of Albany (c. 1340–1420), the son of King Robert II of Scots, and Regent of Scotland from 1388 until his death. Duke Robert"s stronghold has survived relatively unchanged and complete, and the whole castle was traditionally thought of as the result of a single period of construction at this time. The castle passed to the crown in 1425, when Albany"s son was executed, and was used as a royal hunting lodge and dower house.
In the later 16th century, Doune became the property of the Earls of Moray. The castle saw military action during the Wars of the Three Kingdoms and Glencairn"s rising in the mid-17th century, and during the Jacobite risings of the late 17th century and 18th century.
