The stronghold was first mentioned in 1477, in documents given by King Matthias Corvinus by which he allowed Kristofor and Ivan Konjski to build a fort in Selnica. The stronghold was different from others in Croatia. While strongholds (forts) were typically built on high ground, for the advantage of height, the stronghold at Konjščina was Croatia's first wasserburg (water castle) a fort surrounded by much water.
