Albersdorf is a village in the district of Dithmarschen, in Schleswig-Holstein, Germany. It is situated near the Kiel Canal, approx. 14 km southeast of Heide. The place was first mentioned in 1281 under the name Aluerdesdorpe, meaning "village of the old custodian." Albersdorf is the seat of an Amt KLG, bearing the same name, in which ten municipalities around Albersdorf are organized. The Archeologic-Ecological Center tries to recreate the cultural landscape of the Neolithic 5,000 years ago, on the area of 40,000 m². The aim is to create a pasture, settled by the first farmers. In 1999 the center has opened a stone age village in which visitors are shown the technics of that time. In the town centre there is the spa park with an open air stage for 2,000 people. In Albersdorf there is the oldest folk high school on German soil, which is still open today. At the time it was founded, Holstein was under Danish administration. In the rest of Germany, folk high schools were not introduced until the formation of the Weimar Republic in 1919.
