The Sonnwendplatz in Ulm presents a modern stone circle often known as the “Swabian Stonehenge.” Twelve stones mark the twelve months of the year.

Created in 1989, the circle has a radius of twelve metres and follows north-south and east-west lines. Its stone gates frame sunlight during the summer and winter solstices.

The arrangement draws on historical stone circles while belonging to an ecological project at a former water reservoir. That project created a dry biotope.

At 600 metres above sea level, Sonnwendplatz opens views across the surrounding landscape and, on clear days, towards the Alps. Several trails connect the spot with the surrounding area.

The site combines solar alignment, a symbolic circle, and a setting shaped by nature and local customs. Traditional bonfires also form part of the place’s recorded local use.

Its twelve stones give the former reservoir a visible structure for seasonal light and ecological renewal. Sonnwendplatz links Ulm’s landscape with modern cultural design.
