Hexenstein, Glacial erratic near Lindau, Germany
Hexenstein is a gneiss boulder positioned roughly 160 meters west of the Lindau railway line in Lake Constance. The rock breaks the water surface during low tide by about 3 feet (1 meter) and displays red warning markers for boat traffic.
The boulder was deposited during the last ice age through glacial movement and forms part of the moraine between Wasserburg and Lindau. Glacial forces carried this massive rock from distant northern regions to its current location.
The name comes from a local legend about a witch who supposedly used the stone to escape across the lake. This story continues to shape how people understand and talk about the place today.
The stone is visible from the shore and is best seen during low tide when it rises above the water. Visitors can observe it from the Lindau waterfront promenade without needing special equipment or travel.
Originally two of these stones existed in the area, but only one remains visible today. The other disappeared over time due to erosion or removal.
