 During the German "Ostsiedlung" migration, maybe under the rule of the Wettin margrave Conrad the Great in the mid 12th century, Storkow Castle was erected.It probably arose at the site of a former Slavic marsh fortress and served as administrative seat of Wettin "ministeriales" ruling over the extended Lusatian lordship ("Herrschaft") of Storkow.With Lower Lusatia, Storkow passed to the Lands of the Bohemian Crown in 1367; it was located near the northern border with the Margraviate of Brandenburg.
