This peaceful lake is a small glacial kettle lake tucked away amongst the rolling hills. Remnants of the last ice age, it is a unique piece of geological history.

FSG Werft, now known as Flensburger Schiffbau-Gesellschaft (FSG) Shipyard GmbH, is a traditional shipyard located directly on the Flensburg harbor. Founded in 1872, it has since specialized in specialty vessels such as RoRo ferries, research vessels, and naval supply vessels. Over the years, FSG has faced numerous economic challenges: After several changes of ownership—including Egon Oldendorff and later investors led by Lars Windhorst—the company filed for insolvency again in December 2024. But instead of spelling the end of the shipyard, the insolvency marked the beginning of a new beginning: In early 2025, the Heinrich Rönner Group took over the shipyard. Since then, it has officially operated as FSG Shipyard GmbH and FSG Design GmbH, under the leadership of Thorsten Rönner. FSG was able to resume production as early as March 2025 – specifically, construction of an LNG-powered RoRo ferry for its customer SeaRoad continued. Completion is scheduled for the third quarter of 2026.

The Port of Flensburg forms the maritime heart of the city of Flensburg and is located at the end of the Flensburg Fjord. It can be divided into the west side, the east side, and the harbor tip, and boasts impressive historical, industrial, and tourist attractions. On the west side is the picturesque Historic Harbor with the "Alexandra," a historic steamship, and the Museum Harbor, where around twenty traditional museum ships can be seen, including the shark cutter Dagmar Aaen. Maritime events such as the Rum Regatta and the Apple Cruise are regularly held there. The east side houses functional harbor areas: the guest sailing harbor with around 168 berths, offering modern amenities such as electricity and water, as well as the fishing harbor and the industrial harbor with quays for handling coal, fertilizer, grain, and scrap. Flensburger Hafen GmbH operates the entire harbor area and handles large volumes of freight traffic annually.  Between the two sides lies the Hafenspitze, an open space that often serves as an event venue or simply invites you to linger – perhaps to play Frisbee or relax by the water.
