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:Trenčín Castle is relatively large renovated castle, towering on a steep limestone cliff directly above the city of Trenčín. It is a dominant feature not only of Trenčín, but also of the entire Považie region. The castle is a national monument.
History of the castle cliff dates back to the Roman Empire, what is proved by the inscription on the castle cliff proclaiming the victory of Roman legion against Germans in the year 179.
Today’s castle was probably built on the hill-fort. The first proven building on the hill was the Great Moravian rotunda from the 9th century and later there was a stone residential tower, which served to protect the Kingdom of Hungary and the western border. In the late 13th century the castle became a property of Palatine Matúš Csák, who became Mr. of Váh and Tatras.
Matúš Csák of Trenčín built a tower, still known as Matthew’s, which is a dominant determinant of the whole building.
