In his ability as supervisor of the Parks division Astronomy venture, writer Duncan Lunan designed and equipped the 1st astronomically aligned stone circle in Britain in over 3,000 years. 'The Stones and the celebs' examines the case for astronomical alignments of stone circles, and charts the advance of a desirable venture with a powerful medical and old history. The paintings was once documented intimately through the artist and photographer Gavin Roberts, and this archive has been additional to on the grounds that -  so a suitable collection of illustrations will carry the undertaking vividly to existence.
