Dùn Morbhaidh, also known as Dun Borbaidh, is a hill fort located on the Inner Hebridean island of Coll.
The early 20th century antiquary Erskine Beveridge stated his opinion that the correct name for Dùn Morbhaidh was Dun Borbaidh; and in consequence, the name which appeared on maps was probably incorrect.
He stated that the fort takes its name from the nearby Eilean Borbaidh, and Traigh Bhorbaidh; and that the local pronunciation was "Borow", or "Borive".
Beveridge noted that "Borive" resembles several other Hebridean placenames; and that it appeared to be derived from the Norse language borg.
Two short lengths of the outer face of this wall are visible, and stand at a maximum height of 0.7 metres (2.3 ft), in three courses.
[2] Beveridge found the remains of midden material, small rounded pebbles, and the abundance of hammerstones (many of which were broken) at the site.
