There was a Benedictine Abbey at Fort Augustus which had been raised to the rank of an abbey, immediately subject to the Holy See, by a brief of Leo XIII on 12 December 1882. Its building was made possible by the financial backing of Lord Lovat. The current bishop of the diocese is the Right Reverend Hugh Gilbert OSB. In area the diocese is approximately one fifth of the land mass of Scotland. Proportionately it has the smallest Catholic population of any diocese in the United Kingdom. In 2006 the Catholic population of 20,000 out of a total population of 700,000 (2.9%) was served by 44 priests and 12 deacons in 41 parishes.
