The special historic significance is based on its uniqueness as a regional building monument. With the completion of the ensemble and the preservation of its equipment the Watermill is truly exceptional in the region. The residential- and farm building, erected in 1817, represents an early stage of a traditional “Vierständerhaus”. The inventory of the residential section origins from around 1900, of the farming section it goes back to the early 19th. Century. The three-storey Watermill Building was erected in 1893. The mill technology and accessories e.g. grinding gear, elevators, strainer and roller mill have been largely preserved and are operational again. This is also the case for the Venetian Saw gate built in 1900. The mill ponds, created in medieval times, the bake house and the former pigsty are also part of the mill ensemble. 

The Mill’s rescued archival documents provide new scientific insights of the regional social- and economic history, dated back to the 18th. Century. Even the original blueprints, construction plans and the Mill’s working books dated back to 1780 are available. The Water Mill Association has been awarded the “Landespreis für Denkmalpflege 2016 /17. In September 2017 the Karoxbostel Mill Association was recognized by the Lower Saxony Ministry of Culture as a “Place of extracurricular learning within an education for sustainable development“. This certification was achieved in honour of the comprehensive program for education, environment and nature carried on the Mill’s premises since 2013. A variety of cultural events have taken place at the mill. Theatre, music, dance, fairy tales and the recognized minority language “Plattdeutsch” (Low German) have their firm slot in the events calendar.

Nearly 1.100 members of the Mill Association are from all walks of life and all ages. They all share the same values gathered from the experience of pulling together a worthwhile result. Hundreds of media reports praising the performance and the commitment of the “Mill-Rescuers”. Many people have realized great satisfaction and praise in supporting the mill project. Moreover, through the versatile use of historic buildings it has become obvious to many people, that personal effort to prevent the decay of monuments like the Mill is worthwhile, meaningful and can be a LOT OF FUN!
