In 1887, John Bartholomew's Gazetteer of the British Isles described Colonsay like this:

Colonsay and Oronsay, 2 islands, Argyllshire, forming the par. of Colonsay and Oronsay, 11,076 ac., pop. 397; pop. of Colonsay, 387; pop. of Oronsay, 10. Colonsay, 8 miles long and from 1½ to 3 miles broad, has a harbour at Schallasaig, 16 miles NW. of Port Askaig, Islay; P.O. ...


An extensive bone cave has been discovered in C. In the N. part of the island is C. House (1722), seat of the M'Neills of Colonsay. Oronsay, separated from C. by a sound only 100 yards wide, and dry at low water, measures 3 miles by 2 miles. It contains the remains of the Austin Priory -- fine ruins, second in interest only to those of Iona.
