The Steinburg near Nannendorp – today Franzdorf – and Linau Castle were already mentioned in 1291 as the seat of the Scharpenberg Knights, who are notorious in Lauenburg's history for their numerous knightly feuds. In 1349, the Lübeckers attacked the Scharpenberg "robber barons" and, within 10 days, conquered and destroyed eight knights' castles in Lauenburg, including the Steinburg.

Here in the forest northwest of Franzdorf lie the remains of a medieval castle. However, only the remains of the ramparts and ditches remain, as well as some debris from fieldstone walls or foundations. The complex has a diameter of around 40m and stands out clearly from the otherwise flat landscape. Interestingly, the castle ruins lie exactly on the district border, i.e. on the border of the former duchies of Holstein and Lauenburg. The castle also gives its name to the municipality of Steinburg, which was created in 1978 from the merger of Eichede, Mollhagen and Sprenge. Coming from the direction of Mollhagen or Sprenge, the forest path appears to end here. For experienced mountain bikers, however, it should not be a problem to overcome the ramparts and ditches and continue the path on the other side towards Franzdorf.

For over 430 years, Ahrensburg Castle has been one of the most beautiful Renaissance castles in Schleswig-Holstein. During this long period there were joys and sorrows for the castle residents, as well as phases of decline and economic hardship instead of wealth and splendor. The castle museum is impressive with evidence of a long history, from the Renaissance to historicism, and modernity is also represented. Today the castle is not only a museum of Schleswig-Holstein aristocratic culture and the landmark of the city of Ahrensburg, but also offers its visitors a variety of opportunities to discover it from completely different sides. https://www.schloss-ahrensburg.de/das-schloss/
