Duart Castle was originally a stone walled rectangular enclosure fortress, founded by the Lord of the Isles. In the mid to late 13th century, Lachlan Lubanach added a keep to the outside of the original curtain wall, enclosing the well. In the 17th century, a three storey first floor hall range and a three storey kitchen range were built within the courtyard. Also Sir Allan Maclean, strengthened the gateway entrance to the courtyard, by adding a two storey gatehouse. Visit pending. 16 miles north-west is Aros Castle.
