Dunnideer Castle

Dunnideer Castle crowns the 268-meter Hill of Dunnideer near Insch, Aberdeenshire, commanding panoramic views across the countryside. Built around 1260, the tower house is recognized as the earliest authenticated example of this architectural type in Scotland, reusing stone from an Iron Age vitrified hillfort dating to approximately 250 BC. The tower measured 15 by 12.5 metres with thick walls, likely featuring a first-floor hall and multiple stories. Visitors today explore the crumbling stone remains set atop the distinctive hilltop with its concentric rings of prehistoric defences clearly visible as high banks and ditches, creating a layered archaeological landscape spanning over two millennia.
