Astronomical aspects of Kreisgrabenanlagen (Neolithic circular ditch systems)-an interdisciplinary approach

Abstract

Since the 1980s, the entrances of a certain form of monumental Neolithic enclosure (Kreisgrabenanlage, KGA) have been discussed in relation to solstice or lunistice directions. In our current project we analyze astronomical orientations in more than 30 KGAs in Lower Austria, and combine virtual reconstructions based on previous magnetic surveys with horizon surveys and astronomical simulation software.
