After I visit places such as Callanish I am always bewildered, as I am sure that I can’t satisfactorily answer any of the obvious questions – why was it built, how was it built, who built it, what was the reason for building it here rather than on any other hillock in the area? Even the question as to when the site was constructed is open to discussion.

Callanish comprises a number of different elements – a stone circle containing a central monolith and a chambered tomb, three rows of stones intersecting with the circle, and an avenue of stones heading roughly northwards away from the circle. All the stones are Lewisian gneiss and were quarried locally.

The stone circle consists of thirteen stones, with an average height of 3 metres. The circle is not quite perfect as the east side is slightly squashed. The circle covers an area of 124 square metres with a diameter of 11.4 metres. The circle was built between 2,900 BC and 2,600 BC making it slightly older than Stonehenge.
