One of the oldest known solar observatories on Earth — seven thousand years old, rebuilt in timber.

Discovered as a cropmark from the air in 1991, the Goseck ring is a 75-metre circular enclosure of concentric palisades with three gates. Two of the gates frame the winter solstice sunrise and sunset as seen from the centre — dated to ~4900 BCE, it is arguably the oldest deliberate solar instrument known. It belongs to a family of some 140 Central European ring enclosures, most of which show similar solstice alignments.

Sky AlignmentsEstablished science

The winter-solstice gate geometry is precise and accepted — foundational evidence that Neolithic Europe systematically watched the sky.

Sacred GeometryA spectrum

Circle-and-gate design repeated across some 140 enclosures suggests, to proponents, a shared geometric canon in 5000 BCE Europe.
