 The current structure was built in 1256 by the counts of Ortenburg, by an arrangement with the lord of Kranj, Ulrich III, Duke of Carinthia.Until 1420, the tower was managed by their ministeriales or vassals, the knights von Chreinburch; in that year, it passed to Count Hermann II of Celje.During the period of Turkish incursions, the tower was incorporated into the city walls.
