Kieselstein Castle is a 13th-century castle in the city of Kranj. The castle stands at what was once a defensible point, guarding the city pier and crossing over the river Sava, and was predated on the site by a round 11th-century keep. The current structure was built in 1256 by the counts of Ortenburg, by an arrangement with the lord of Kranj, duke Ulrik III Spanheim. Until 1420, the tower was managed by their ministeriales or vassals, the knights von Chreinburch; in that year, it passed to count Herman of Celje. During the period of Turkish incursions, the tower was incorporated into the city walls. After the extinction of the Counts of Celje in 1456, it was inherited by the Habsburgs, who sold it in the mid 16th century to baron Janž Khiessl. Khiessl successfully petitioned emperor Ferdinand I for the right to rename the castle after himself, and also expanded the tower into an L-shaped castle, giving it its present appearance.
The Khiessls soon sold the castle to Franz the noble Moscon; later owners included the Ravbar, Apfaltrer, Auersperg and finally Natalis Pagliaruzzi noble families. In 1913 the castle was purchased by the state. Between the world wars, it housed government offices; after World War II it was (somewhat redundantly) nationalized. In 1952, the building was renovated according to plans drawn up by the architect Jože Plečnik.
Today the renovated building houses the Kranj Municipal Agency for the Protection of Natural and Cultural Heritage, as well as the Upper Carniola Museum.
References:The Jan Hus Memorial stands at one end of Old Town Square. The huge monument depicts victorious Hussite warriors and Protestants who were forced into exile 200 years after Hus, and a young mother who symbolises national rebirth. The monument was so large that the sculptor designed and built his own villa and studio where the work could be carried out. It was unveiled in 1915 to commemorate the 500th anniversary of Jan Hus' martyrdom. The memorial was designed by Ladislav Šaloun and paid for solely by public donations.
Born in 1369, Hus became an influential religious thinker, philosopher, and reformer in Prague. He was a key predecessor to the Protestant movement of the sixteenth century. In his works he criticized religious moral decay of the Catholic Church. Accordingly, the Czech patriot Hus believed that mass should be given in the vernacular, or local language, rather than in Latin. He was inspired by the teachings of John Wycliffe.
