In 1230, the Slavic settlement was first mentioned in the Ratzeburg tithe register as Linowe or Lynowe. The place name goes back to Old Polabian *Linov and is a combination of *lin "tench" and the possessive suffix -ov and means settlement near the tench. Linau is of Slavic origin and lies on the "Limes Saxoniae", the former border between Saxons and Slavs, which enters the administrative area here. According to historical research, it can be assumed that the then "Lynowe" existed as a settlement much earlier. Linau Castle was destroyed in 1291, and the second castle in 1349. The remains of the castle complex are now more clearly visible again, as the foundation of the complex was restored as authentically as possible in a very complex operation in cooperation with the State Archaeological Office. The complex thus gives visitors an idea of its former importance. It is the only castle ruin of its kind in southern Holstein. Linau is located on the edge of the Hahnheide nature reserve and local recreation area, directly on the district border with Stormarn. The community had 543 inhabitants in 1939. After the unspeakable war, there were 1031. Many of them have accepted the community as their new home. Linau has an intact, diverse club life, including a motivated volunteer fire department. This is not least and especially due to the initiative of the Linauers. https://gemeinde-linau.de/unser-dorf/ https://de.wikipedia.org/wiki/Linau

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/

Today we visited the reconstructed castle. The reconstruction probably only affects the old keep, which was built a few meters thick with field stones. We would not have expected the castle itself to be here, but it is worth a short detour. Times must have been quite dangerous here back then, since some old castle ruins such as Cecilieninsel and the other castle ruins next to Cecilieninsel are also there. Incidentally, the way to the farm dog was blocked off, which means that it is no longer possible to get there. Next to the castle there are some ponds where fish was/is bred. If you want to enjoy the view, you can eat in the pond restaurant. But I don't know if this is still open at all, since there was no card on the house.

The Schlosskirche Ahrensburg is a listed building on the market square in Ahrensburg. The church was built around 1595 at the same time as the Ahrensburg Castle. The simple, post-Gothic brick building consists of a long, rectangular hall.

The Castle Church is located directly opposite the Ahrensburg Castle. It was built in red brick in the post-Gothic style. While the consecration took place in 1596 and the altar and seating from that time are still there today, the church was also given a Baroque interior in the 18th century.
