Strzelce Opolskie Castle was a former residence of the Dukes of Opole located in Strzelce Opolskie. The castle was burned down during World War II by the Soviets and remains in ruins to this day.
The town of Strzelce Opolskie was situated on the trade route Kraków–Wrocław–Dresden. The settlement was initially surrounded by a thick forest. An original wooden hunting lodge was probably replaced by a stone structure in the 13th century. The castle was first mentioned in Liber fundationis episcopatus Vratislaviensis as Castrum Strelecense. The document is believed to be compiled in 1305.
The castle was built on a simple rectangular plan measuring 16,1 x 13,9 m and was, in fact, a limestone tower. In 1323 Albert became the duke of an independent Duchy of Strzelce/Strehlitz. He carried out extensive renovations to the castle and built a series of fortifications and a moat around it. After his death the castle and the duchy was taken over by the Piasts of Niemodlin and after the extinction of the line in 1382 it was passed to the Piasts of Opole. The dynasty owned the castle up to its extinction in 1532.
In the first half of the 16th century the castle was in very poor condition. From 1562 to 1596 major renovation works were carried out. From the middle of the 17th century to the beginning of the 19th century it was in hands of the Colonna family. The castle's heyday came after 1815 when Andreas Renard took its ownership and made it his main residence. An English-style landscape park was created in 1832. In 1840 Andreas Renard extended and remodelled the palace adding an adjacent tower and building horse stables near the west wing.
From 1932 to 1945 the palace was possessed by the Castell family. On 21 January 1945 Soviet troops set the town and castle on fire. The building remains in ruins to this day.
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.
