Burg Fluhenstein, Medieval castle ruins in Sonthofen, Germany.
Burg Fluhenstein is a medieval castle whose ruins sit on elevated ground near Sonthofen, overlooking the Allgäu valley. Sections of stone walls and foundations remain visible, showing how the defensive structure was once organized and built.
The fortress was built in medieval times to protect the trade routes running through the Allgäu, which mattered greatly to local rulers. Over time it was abandoned and gradually crumbled into the ruins visible today.
The site reflects how medieval rulers used fortress locations to assert power over the surrounding valleys and trade networks. Walking through the ruins, you sense the strategic importance this place once held in organizing the region's daily life and protection.
Marked paths lead to the site from Sonthofen, and information panels along the way explain the layout and purpose of the fortification. The vantage point offers clear views across the valley, making it easy to see why this location was chosen for defense.
The ruins are more than just remains from the past; they are an active excavation area where researchers continually uncover new details about how people lived in medieval Bavaria. This makes the site a living bridge between history and ongoing discovery.
