In the Heimatstube Trebbin, which is looked after by the Heimatverein Trebbin, there are extensive collections on the history of Trebbin. Many people from Trebbin and friends of local history have donated documents and other historical paraphernalia to the Heimatstube to enable a varied presentation of the historical development of the town. In addition, the Heimatstube hosts changing exhibitions dedicated to individual themes in the development or anniversaries, e.g. Trebbiner associations or Trebbiner crafts. Not to forget Hans Clauert, Märkischer Eulenspiegel from Trebbin. He, too, has his place in the Heimatstube. His stories and testimonies of his work can be read here.
