The Lower Saxon Mill Road (German: Niedersächsische Mühlenstrasse) is a holiday route that guides visitors to watermills and windmills in the north German state of Lower Saxony and thus links the interests of historic monument conservation with those of the tourist industry.
The mills of the Lower Saxon Mill Road are marked with the emblem (a sketch of the Hüven Mill in the Emsland) of the Lower Saxony and Bremen Mill Association (Mühlenvereinigung Niedersachsen-Bremen) and are furnished with an information board that describes both the history and the features of the individual mill.
The mills on the Lower Saxon Mill Road are of various types: Most of them are watermills and windmills. Some have been converted into homes, others are used as museums or are still in service. Several of the mills can only be viewed externally. In the International Wind- and Watermill Museum at Gifhorn a ship mill may also be visited. There are horse mills in the Cloppenburg and Hösseringen Museum Villages. In several buildings, not otherwise identifiable as mills, there are motor mills (Motormühlen); a building in the village of Einen near Goldenstedt houses a former korn distillery with a steam mill. Hydropower stations like the Oldau power station on the river Aller also count as 'mills' for the purposes of the Lower Saxon Mill Road.
