Bullaun

A bullaun (Irish: bullán; from a word cognate with "bowl" and French bol) is the term used for the depression in a stone which is often water filled.

[1] In May 2012 the second cursing stone to be found in Scotland was discovered on Canna and drawn soon after by archaeological illustrator Thomas Small.

[10] Bullauns are not unique to Ireland and Scotland, being also found on the Swedish island of Gotland, Lithuania and France.

[11] Possibly enlarged from already-existing solution-pits caused by rain, bullauns are reminiscent of the cup-marked stones which occur all over Atlantic Europe, and their significance (if not their precise use) must date from Neolithic times.

Many of the granite boulders on this hill have what appear to be erosion formed concavities, usually pear shaped, which indicate bullaun in formation.
