Schloss Rietzneuendorf
At the end of a cow pasture, you can find all sorts of things. In the little village of Rietzneuendorf near Berlin, it is a castle. In fact, the cow pasture, with no cows standing on it when I visited, runs right across its access, which I thought may be a hint to its history (as there are also cow byres next to it) and being used as part of a people-owned enterprise during GDR times but sadly it's terribly hard to find anything about its history.
The village seems to have been founded in 1685 by Wilhelm von Stutterheim and then later sold to the King of Prussia, Friedrich Wilhelm I. Since then it was used as a farming area. Either around 1860 or 1885, sources vary about his, a castle was constructed on the site. Either around that time or in 1893 - again, sources vary - it received its current Neo-Renaissance appearance. The castle seems to have been used by the administration of the estate. While yours truly was able to dig up some names seemingly connected to it, none of them…
