Schilteck Castle

North above the town of Schramberg in the district of Rottweil, the castle ruin Schilteck stands as a testament to medieval defensive architecture. Once strategically positioned at the valley exit, it likely served to monitor the Schiltach valley and is now a freely accessible historical monument.
