Rodenberg is a town in the district of Schaumburg, in Lower Saxony, Germany. It is situated on the northwestern edge of the Deister hills, approx. 10 km east of Stadthagen, and 27 km west of Hanover.Rodenberg is also the seat of the Samtgemeinde Rodenberg ("collective municipality").GeographyThe town of Rodenberg lies between the Deister, Süntel and Bückeberg ridges. The Rodenberger Aue and Steinaue streams flow through the town. The "old Rodenberg" hill, which gives the town its name, with its landmark windmill, rises to the west of the town. Since 1974, the parish of Rodenberg includes the formerly independent parish of Algesdorf. The neighbouring village of Grove, with its church, was amalgamated with Rodenberg in 1834.HistoryThe neighbourhood of Rodenberg was already settled in prehistoric times, inter alia by the Celts and Saxons. This is also witnessed by some barrows in the vicinity. The name Rodenberg refers to a hill to the west of the town, and the name does not refer to a clearing but to the red colour of the hill: "roter Berg".According to the earliest record of the town, the predecessors of the Counts of Schaumburg erected a castle or peel tower here in 930; unfortunately no more details are known.It is presumed that the moated castle was established by Adolf IV, Count of Schaumburg between 1228 and 1240, and that the previous castle of 930 was located on the so-called "old Rodenberg" to the west of the town.
