To pique the interest of anyone interested in history and Slavic people in what are modern-day German lands. That is the main link. It’s got a bit of fascinating information there which makes for good reading.
Here’s the link to Groß Raden itself and its information (in German). That’s actually more informative for me, to be honest.
Also of interest to me in general, as my family is mostly Czech and German. So a mix of Slavic and German heritage. I might have to delve deeper into this topic in the future.
