According to legend, Hangman's Rock, on the slopes of Beinn Eibhne, at the southern tip of Colonsay, was used for public hangings, performed by passing a rope through a hole in a natural rock outcrop.
Though there is no firm evidence to support this fact, it seems likely enough, given the shape of the rock, and the historical culture of the remote Scottish islands. Certainly, Hangman's Rock is striking, and might well have suited the purpose of a gallows quite nicely!
The location overlooking The Strand and Oronsay is quite simply stunning.
