The name "Blaumühle" is not, as one might assume, due to the blue-black slate cladding, but rather to the activity of "Blauens" or "Bleuens", ie "beating". Not only the blue mill found here, but also other mills with this name were in their early days hammer mills or "hammer mills".
First mentioned in 1631 as "Blomohle", the blue mill has influenced the fate of many families over the centuries. The last grain miller residing here, Johannes Grebestein, could not feed the mill, so he left it in 1906. In the same year on 09/21/1906 it was read in the "Tageblatt" that Mr. brush manufacturer Hauck from Eschwege had acquired the blue mill in order to set up a branch of his factory there.
