Tarbert Castle is found perched on top of the hill overlooking Tarbert Harbour .

Now owned by the Tarbert & Skipness Community Trust , work to improve access for visitors is currently under way .

The castle is a monument of national importance due to the reinforcements and enlargement made to the castle by Robert The Bruce , King Of Scotland in 1325 .

The grass around the castle is maintained by a flock of Hebridean black sheep that graze in the surrounding area .
