Clach an Truiseil was possibly once part of a larger stone circle and avenue, dating to the Neolithic period, 4,500 years ago. If you explore the drystone wall adjacent to the stone, you will find other massive stones which may also have been part of the circle. There are several local legends surrounding the stone. One suggests that it marks the site of a great battle between the MacAulays and the Morrisons, whilst another indicates that it was a sea-marker in pre-historic times.
