The windmill was built in 1821. In 1905, during a thunderstorm, it caught fire and burned down. The masonry, which was partially reconstructed, has been preserved. The octagonal Mühlenstump stands on the densely wooded Mühlenberg in Rehburg. Several paths and a main entrance lead up there.

Hagenburg Castle, the forerunner of Hagenburg Castle, was first mentioned in a document in 1369 as Hagenborch. It probably goes back to the Counts of Schaumburg, when they set foot on the Steinhuder Meer in the 14th century. The castle was probably used in the early 14th century to secure the settlement of Hagenburg, which was built in the second half of the 13th century. From the 14th century onwards, the castle was often mortgaged and later served as the administrative seat of the Hagenburg district. In 1518 the brothers Anton and Johann zu Holstein-Schaumburg were enfeoffed with the castle by the Hessian landgrave. The lords of Heimburg sat here as their ministerials until 1558, after that Ludolf Klencke was. In 1558 Klencke had a gatehouse built and the castle rebuilt. In the living quarters he installed a spiral staircase. In 1574 his son Ernst Ludolf arranged for some renovations and the construction of a sheepfold.

Located on the Mühlenberg hill, the Rehburg windmill was a landmark that could be seen from afar. On July 1, 1905, the mill was struck by lightning, which reduced the shingled wooden structure and the surrounding gallery to ash. A national emblem can be seen in the keystone of the archway: "G.R.III, 1821". The initials refer to "Georg Rex III", the then King of Hanover. Today only the mighty octagonal stone substructure bears witness to the once beautiful building. Source: https://www.mittelweser-tourismus.de/poi/muehlenruine-rehburg/
