Burgruine Wolfstein, Medieval castle ruins near Landshut, Germany

Burgruine Wolfstein is a ruined hilltop castle at 450 m above sea level on the southern Isar slope in Landshut's Auloh district. Its remains include foundation walls and three rectangular barrel-vaulted cellars from the 16th century, the largest with a central column. A farmhouse built around 1800 incorporates a 15–18 m long, 1.5–2 m wide castle wall as its west end wall.

The castle began as a noble residence and reached importance when Konradin, the last male Staufer heir, was born here in 1252. In the 14th century, Emperor Louis IV used the property as a hunting lodge and gave it to his second wife as part of her dowry.

The site preserves the memory of Konradin, one of the last representatives of the Staufer dynasty, marked by a memorial plaque on the old estate. You can observe how the castle's original walls were incorporated into the farmhouse built in 1800, layering two different periods in one structure.

The ruins lie southwest of Niederaichbach in eastern Landshut and are protected as an archaeological monument. Access is on foot via local walking paths, and the site is open to visitors year-round.

The memorial plaque to Konradin on the farmhouse dates from 1873, long after the castle was dismantled. The three barrel-vaulted cellars, the largest with a central column, survive from the 16th century, when the site was already being quarried for stone.
