The first mentioning of Niesytno Castle dates back to the 13th century, but it is not known by whom it was built. Legends tell of occupation by Hussite and mercenaries, and therefore it was also named Zakątek Strachu or Angstwinkel (Polish and German for 'corner of fear'). From the second part of the 15th century until the 17th century, the castle was inhabited by the 'von Zedlitz' lineage. It has been a military defense structure for several times. Later, the castle became a renaissance palace.
During the Second World War, German airmen (the luftwaffe) resided in the palace, preparing themselves for battle at the eastern front. The resistance used the palace as home during summer season. At that time it gradually turned into ruins. Thereafter, it was owned by the automobile manufacturer 'Fabryka Samochodów Ciężarowych' from Lublin. Some repairs were carried out at that time, though neighboring population stole the building materials little by little. The palace weathered until 1990.
On 2 July 1990, while belonging to Elizabeth Zawadzkie-Malickiej from 1984, it burned down due to arson, which ruined the palace. The current state of the buildings yield even more damage. Parts of the brick walls remained after the fire.
The buildings are not open for public, but it is possible to walk around the premises and get a glimpse of what is left of the buildings. The castle is located on a hill surrounded by forest, and the remainders of the tower of the castle are visible from some distance. Most of the other parts of the ruins are hidden behind trees. Some caves can be found around the ruins, which once probably were basement and other rooms.References:
Medvedgrad is a medieval fortified town located on the south slopes of Medvednica mountain, approximately halfway from the Croatian capital Zagreb to the mountain top Sljeme. For defensive purposes it was built on a hill, Mali Plazur, that is a spur of the main ridge of the mountain that overlooks the city. On a clear day the castle can be seen from far away, especially the high main tower. Below the main tower of the castle is Oltar Domovine (Altar of the homeland) which is dedicated to Croatian soldiers killed in the Croatian War of Independence.
In 1242, Mongols invaded Zagreb. The city was destroyed and burned to the ground. This prompted the building of Medvedgrad. Encouraged by Pope Innocent IV, Philip Türje, bishop of Zagreb, built the fortress between 1249 and 1254. It was later owned by bans of Slavonia. Notable Croatian and Hungarian poet and ban of Slavonia Janus Pannonius (Ivan Česmički) died in the Medvedgrad castle on March 27, 1472.
The last Medvedgrad owners and inhabitants was the Gregorijanec family, who gained possession of Medvedgrad in 1562. In 1574, the walls of Medvedgrad were reinforced, but after the 1590 Neulengbach earthquake, the fortress was heavily damaged and ultimately abandoned. It remained in ruins until the late 20th century, when it was partly restored and now offers a panoramic view of the city from an altitude of over 500 meters.
