Braunenberg, Summit in Ostalbkreis district, Germany

Braunenberg is a 685.3 m high summit on the eastern Swabian Jura, east of the Wasseralfingen district of Aalen. It is the most prominent elevation of the Flexner ridge (725.4 m), whose foothill it forms. From the side, its stepped relief is clearly visible, shaped by layers of Brown and White Jurassic rock.

The mountain formed during the Jurassic period when this region lay beneath a shallow sea that deposited abundant limestone sediments. These ancient layers now form the visible rock formations that tell the geological story of the landscape.

The Wasseralfingen mining trail, laid out in 1979, leads past the former Wilhelm I mine, which has been open since 1987 as a visitor mine called the "Tiefer Stollen" and also serves as a healing gallery. The fossil-rich limestone quarries of the upper layer remain visible on the mountain.

The Wasseralfingen mining trail, laid out in 1979, leads up the mountain past the former "Wilhelm I." mine, which has been open since 1987 as the "Tiefer Stollen" visitor mine and also serves as a healing gallery. Remains of the cable car foundations can still be found along the former route.

The cable car that carried iron ore from the Braunenberg to the Wasseralfingen smelter was completely dismantled after the mine closed, but foundation remains can still be found along its former route. The fossil-rich limestone quarries on the upper slopes, where the smelting lime was broken, are still visible today.
