After being discovered less than 25 years previous. Goseck Circle was recalibrated on Dec 21, 2005. During Winter solstice. Using 1675 2.5m high oakpoles.

Goseck Circle is an archaeological site located in Goseck, Germany. It is a Neolithic structure that consists of a circular enclosure made up of concentric ditches and banks, with a diameter of about 75 meters (246 feet). The site dates back to approximately 4,900 BCE, making it one of the oldest known solar observatories in the world.

The Goseck Circle was discovered in 1991. Along with others (link) in central Europe during an aerial survey. It was subsequently excavated. The structure’s purpose is believed to have been related to astronomical observations and the tracking of celestial events, particularly the winter and summer solstices. The entrance to the enclosure aligns with the sunrise during the winter solstice, while two wooden palisades inside the circle align with the sunrise and sunset during the equinoxes

A circular v-shaped moat of up to 1.8 m depth surrounds the site. Its soil used to create a rampart on the outside. Gating the way, to create perimeter and keep others out. The diameter of the moat is 75 m, measured from its external border. Inside, double wooden palisade stand. Inside the circle, entry to the site is in symentry to the north, southwest, and southeast. No traces of internal buildings were ever found. One thing is for sure. Its large circular oak walls and ditches stood.

In addition there were small gaps in the palisades allowing viewing or access. The moat followed the three main entries outward (see diagram). The entrances in the inner palisade were narrower than those in the outer, which in turn, were narrower than the gap in the moat.

The circle is considered a significant archaeological find because it provides evidence of advanced astronomical knowledge and complex architectural planning during the Neolithic period. It suggests that the people who built the site had a sophisticated understanding of celestial movements and likely placed great importance on celestial events in their cultural and religious practices.

The site has no signs of fire or other destruction. Why it was abandoned, is unknown.

Today, Goseck Circle is open to visitors in Goseck, Germany. A sense of journey to its original neolithic form. The site has become a popular tourist attraction and serves as an educational site for learning about ancient astronomy and the cultural practices of the Neolithic people.
