The castle was once used as a high-security state prison, housing notable political dissidents of the Duchy of Württemberg.
It was never conquered by military force but was instead systematically demolished by the ruling authorities in 1765.
The site sits at an elevation of approximately 694 meters above sea level.
The castle grounds cover an area of approximately 2.5 hectares, making it one of the largest castle ruins in southern Germany.
The fortress played a significant role in the 'Helfenstein' inheritance dispute during the 13th century.
Burgruine Hohenurach is a sprawling 11th-century fortress ruin situated on a steep Jurassic limestone cliff overlooking the Erms Valley. It served as a vital stronghold for the Counts of Urach before being converted into a state prison by the Dukes of Württemberg. The site features extensive curtain walls, preserved defensive towers, and vaulted cellar chambers accessible to visitors. Visitors reach the ruins via a steep hiking path originating from the nearby Urach waterfall area. The structure occupies a strategic position on the Swabian Alb, offering expansive vistas of the surrounding karst landscape. Remnants of the former palace and secondary fortification rings remain visible today. The castle was intentionally dismantled in the 18th century to prevent it from being used by enemy forces.
