Jurisics Castle, named after Croatian nobleman Nikola Jurišić. The oldest part was built in the 13th century. The inner castle originally of Gothic style was extended later on. This building complex served as an estate castle and was also converted in the Renaissance and Baroque era. The character of the two islands still can be observed: it is visible that the fortress and the interior of the castle were surrounded by a moat.
During the Little War in Hungary, Pargalı İbrahim Pasha under the command of Suleiman the Magnificent laid siege to the castle in 1532. Jurišić and less than 1000 men defended the castle for 25 days without any artillery, despite 19 assaults.
References:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
