The post gives a new method to registrate each rock of the Stonehenge prehistoric site. The technique includes a digital laser system that shows the marks that the workers made in the rocks. In almost all the cases, the rocks had a side with a very pulish surface. The opposite site, for a contrary, shows a less worked surface. The main reason for a pulish surface is to reflect the sun rays during the winter and summer solstices. So, the site has astronomical connections, and the rocks of the walls plays a very important role in this connections.

During the Middle Age, and later, many people took rocks from the site and transported them into their village to construct their homes. So, now is almost impossible to identify all the rocks that belonged to the site. Some archaeologist that visited the site said that almost all the rocks of the place were worked in their surfaces and this, make the site as a very special site.

The 3D laser scan also showed some graffiti that were done to the rocks, around 3.500 years ago, belonging to Victorian and Georgians visitors. The scan also revealed that people of the Bronze Age engrave figures like small axes in many places. There are around 170 of them.
