The „Museumshafen Oevelgoenne (museum harbour of Oevelgoenne) was founded by a private association in 1977 at the fairy pier of Neumuehlen. It offers a mix of historic professional sailing ships. For example an old fire ship, which was in service between 1888 and 1977, an icebreaker, a swimming crane, the old harbour police boat and a harbour fairy. All of them are still roadworthy. At the pier there is also the rebuilding of a historic shelter like it was used around 1900 at all piers in the harbour. Today it is used by the association.
