|The Goseck circle consists of a circular Henge-construction with a diameter of 75m in the district of Weissenfels in Saxony-Anhalt. The reconstructed observatory was opened on the winter solstice, 21 December 2005, with great pageantry, including a spectacular fireworks display.|
There are now two concentric wooden palisades, each 2.5 metres high, as well as a ditch and an earthen wall. The 2,300 oaken poles were erected on the same site over a seven-month period.
The first evidence of human settlement is from the Neolithic period. The Goseck circle is dated to approximately the 5th millennium BC.
It was discovered by aerial photographs from the 1990s and, since 2003, regarded as the oldest observatory in Europe.
