Schloss Rheden
The Rheden family is an old noble family of the Prince-Bishopric of Hildesheim. Firstly mentioned in 1251, they take their name from a tiny village south-west of Hildesheim in Lower Saxony. In the same village, Schloss Rheden is located. The castle was built in 1729 and received its current appearance through renovation works in 1899. Likely through inheritance, the castle ended up in the hands of the Counts of Dohna who still own the estate though it seems that the castle has been converted into a bunch of condominiums.
Good to know:
A golf club including a restaurant is located in one of the castle's outbuildings while the Schloss is privately owned and not visitable.
