On the crest of the Jakobsberg towards the southwest and just under 650 m (as the crow flies) west of the Bismarckburg Inn at a height of NN are the ruins of the Schlageter Monument. Built in 1933/34, it was never completed, probably for ideological reasons. On a plinth was a large cross. This only stood there for a short time before being moved to Minden's North Cemetery (Nordfriedhof). There it was integrated into a memorial for those who fell in the First World War.
