Summary

The medieval castle on the small tidal island of Eilean Donan, heavily restored in the early 20th century, may have occupied the site of an earlier fort, though evaluations in 2008 and further excavation in 2009 and 2010 did not encounter any remains of it. A length of collapsed walling on the NW side of the bridge that now connects the island contains fragments of vitrified stone, though the wall itself probably belongs to the more recent defences.
