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.

Museum harbor with the best fish stall in the guardhouse. Waiting in line is part of the experience, but it's worth it.

The harbor in Flensburg is definitely a highlight; there's so much to see and plenty of opportunities to enjoy delicious fish. My favorite part is the many boats, both old and new.

Frörup has an old water-powered mill, driven by the Treene River and used for grinding grain. It was probably established in the 13th century. Later, the mill belonged to the Cistercian monastery of Rüde. The abbot there ceded the mill to the King of Denmark in 1543. Today, the mill is privately owned, and the waterwheel is used only for generating electricity. Unfortunately, visits are not possible. https://de.wikipedia.org/wiki/Fr%C3%B6rup

On April 1, 1971, the previously independent municipalities of Stenderup near Havetoft and Süderschmedeby were incorporated into the new municipality of Sieverstedt. Süderschmedeby was first called Smedebu around 1342, in contrast to Norderschmedeby near Bau north of the border, which was simply called Smedeby. In 1472, it was called Smedeby, in 1538 Smeby, and in 1681 Schmedebui. Names ending in -by probably date back to the late Iron Age or Viking Age and are of Danish or Swedish origin. The name can be interpreted as the blacksmith village. Here, bog iron ore was found in the fields and cast and forged in special furnaces. Just like today, the municipality was already located in a "traffic triangle" back then, to which the early and very numerous settlement can be traced, namely the eastern Heerweg or Ochsenweg, the Stapelholmer Weg, and the Angelboweg. The coat of arms blazon: "Divided by blue and green, lowered by a narrow golden wavy bar. Above, a golden stone grave consisting of three supporting stones and a ceiling stone, covered with a red miter. In the upper corners, accompanied on the right by a small golden anvil, on the left by a small golden key." The coat of arms of the municipality of Sieverstedt combines various historical symbols from the history of the settlements of Sieverstedt. The anvil refers to the blacksmithing tradition of Süderschmedeby, and the key to the old historic church of Sieverstedt. The central element of the coat of arms is the stylized Poppostein (popped stone) with a bishop's mitre in the center, which refers to the legend of the so-called Poppostein (popped stone). The wavy line in the lower section symbolizes the Bollingstedt Au, which flows through the municipality. The colors of the coat of arms refer to the town's affiliation with the Duchy of Schleswig. https://de.wikipedia.org/wiki/Sieverstedt
