Evidence+of+astronmical+abilities

There is alot of evidence found in pre-historic britain but the most prodomiately known site is Stonehenge. Stonehenge is composed of earthworks surrounding circular setting of large standing stones. The clearest case in question is that of the Neolithic long cairns or long barrows, which by their very nature define a clear orientation. The fact that many of the alignments in South Wales appear to indicate astronomical targets does not in itself prove that this was the intention of the monument's builders.
