Laubenbergerstein Castle Ruins

Highlight • Castle

The late medieval castle Laubenbergerstein was founded in the 12th century by the bishops of Augsburg. It is located on the main road in the north of Immenstadt and guarded once the important Illerübergang and the associated customs station. The castle stands on a small hill that climbs in five minutes.
From the formerly mighty plant are still two towers and numerous wall remainders, which let the former entire structure well understand.
The castle ruin was renovated over more than 30 years by the home association and can be visited at any time. The towers are accessible at the Castle Walks and Castle Festival.

View of Niedersonthofener See, Grünten, and the Allgäu Alps

Highlight • Viewpoint

Before going downhill towards Memhölz, you can stop here on the top right and have a nice view of the Niedersonthofener lake, the Grünten and the Allgäu Alps. It's worth it!
