Dun Ardtreck is a D-shaped dun, or "semi-broch", located on the Minginish peninsula of the west coast of the island of Skye, Scotland. It is situated on a rocky knoll on the edge of a cliff overlooking the sea, near the small village of Ardtreck and close to Portnalong and Fiskavaig. The landward side is bounded by precipitous rock faces except on the southeast where a small cleft was used for an outer gateway. Duns were fortified settlements common in Scotland during the Iron Age, and this example dates to between 500 BC and 1 AD.
