Dùn Anlaimh

Dùn Anlaimh, also known as Dùn Amhlaidh, and Eilean nan Cinneachan, is a crannog (an artificial island), located within Loch nan Cinneachan on the Inner Hebridean island of Coll. Upon the crannog there are the remains of walls and several buildings. These remains are not unlike those of other fortified islands found throughout the Outer Hebrides, and it is likely that Dùn Anlaimh dates from the late Middle Ages.
