Take a moment and sit on the warm concrete steps right by the water. As the wind gently brushes through the dense, green reeds and the stalks softly rustle in rhythm, you can leave everyday life behind for a moment. The gentle green of the biotope, the vibrant activity of nature, and the tranquility of this place invite you to take a deep breath and let your soul dangle.

Via this wooden bridge you can cross from the green side 🌳 over the moat to the castle 🏰 of Ahrensburg. The iron gate on the bridge is not always open. Look at the photo with the opening hours 😉.

There are always changing exhibitions here. The ambiance is great and rustic. There is a large event hall and a drinks counter in the anteroom if you enter the building from the back.
