The Castle of the Masovian Dukes in Czersk was built on the turning point of the fourteenth and fifteenth century by Prince Janusz I. When the Masovian land became part of the Kingdom of Poland - which was under the rule of Queen Bona Sforza. Primarily, the castle had three towers, one of them - being four-sided, was used as the main gate house.
During the war with the Swedes, in 1656, the castle became partly ruined. The retreating land army, close to Warta, under Stefan Czarniecki"s commandhad captured the stronghold and had devastated it. The castle went through a reconstruction between 1762-1766, when Marsza³ek Franciszek Bieliñski had commanded the reconstruction of the stronghold. However, due to the Prussian Partition, the Prussian leader had ordered for the demolition of the castle"s defense walls, reducing the stronghold"s military importance. From that time, nobody had every again took on the reconstruction of the castle. From the once mighty stronghold, all of the towers; a brick bridge from the eighteenth century; and the north and east wing of the castle had all survived.
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.
