Burg Laubenbergerstein, Medieval castle ruins in Immenstadt, Germany

Burg Laubenbergerstein consists of stone ruins perched on a wooded hillside north of Immenstadt, overlooking a crucial river crossing. The site still shows traces of defensive walls and towers that once guarded this strategic valley location.

Bishops of Augsburg built this fortress in the 12th century to control a river crossing and collect payments from merchants. The castle was eventually abandoned and declined into the ruins visible today.

Since 2013, members of the "Laubenberger Ritter" have appeared at the castle in historical costume, helping the Heimatverein Immenstadt maintain the ruins and showing visitors medieval life. The name Laubenbergerstein comes from the Lords of Laubenberg, first documented here in 1241 with Heinrich von Laubenberg zu Laubenbergerstein.

Hikers can reach the ruins via marked trails leading up from Immenstadt, where information panels explain the site. The best time to visit is during warmer months when paths are dry and easy to walk.

The castle chapel stood southeast of the gate tower above the main gate until it largely collapsed into the neck ditch. A late Gothic altar wing from the chapel is kept at Rauhenzell Castle, the seat the Laubenberg family moved to in 1559.
