Hinba
Hinba is an island in Scotland of uncertain location that was the site of a small monastery associated with the Columban church on Iona. Although a number of details are known about the monastery and its early abbots, and various anecdotes dating from the time of Columba of a mystical nature have survived, modern scholars are divided as to its whereabouts.
The islands of Eileach an Naoimh and Jura are the most likely candidates, although Seil, Canna and Oronsay are also possibilities.
