The Castle in Siewierz was built in the first half of the 13th century on a man-made hilltop, where formerly stood a wooden fortress. The oldest of the stronghold"s fortifications come from the 15th century. In 1443 Duke Wac³aw I of Cieszyn sold the town and the castle to Kraków"s bishop Zbigniew Ole¶nicki. The Bishops of Kraków expanded the castle and its fortification walls. The castle began to crumble in the seventeenth century, and Swedish raids quickened its deteriorating. After The Deluge the castle was rebuilt by that didn"t stop it from deteriorating and turn into a ruin. The last resident of the castle, Feliks Pawe³ Turski, left the residence in 1800. The only reason the building did not diminish is due to extensive reconstruction and renovation works in the 1950s, 1970s, and 1990s.
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.
