Christmas trees in Husum church. Husum is the capital of Nordfriesland in Schleswig-Holstein, Northern Germany. The town was the birthplace of the novelist Theodor Storm. It’s home to the annual international piano festival Raritäten der Klaviermusik. Husum was first mentioned as Husembro in 1252. Like most towns on the North Sea, Husum was always strongly influenced by storm tides. In 1362 a disastrous storm tide, the “Grote Mandrenke” flooded the town and carved out the inland harbor. Before this, Husum was not situated directly on the coast. The people of the city took advantage of this opportunity and built a marketplace, which led to a great economic upturn. The town is located 80 km from Kiel, 140 km from Hamburg, and 40 km from Flensburg.
