The three pillars, known locally as 'The Three Sisters', stand as a monument to one of Largs' most famous sons. Sir Thomas Makdougall Brisbane. The pillars are remnants of the astronomy Observatory built in 1808 at Brisbane House, the first of three established by Brisbane. His favourite Observatory seems to have been the Largs one, as he did his main work from it. To help with his observations, Brisbane built 'The Three Sisters' here on Green Hill with a Meridian pillar midway between his Observatory and the 'Sisters', which enabled him to establish a true North-South line in the sky for his telescope measurements. In Brisbane Glen, there is another smaller pillar in a field near the site of his Observatory. This was cylindrical, with a triangular top which had a hole, through which the 'Three Sisters' could be sighted and due North established.
