Duntulm Castle was originally an Iron Age broch or dun, which later became a Pictish fort. Standing on a promontory, in the 15th century the MacLeods founded the stone castle, when adding a four-storey tower house protected by a rock-cut ditch. In the early 17th century the MacDonalds of Sleat, moved here from Dun Scaith and added the range of buildings around a courtyard. By the early to mid 18th century the abandoned castle, was providing material to rebuild Monkstadt House. 25 miles south-west is Dunvegan Castle.
