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:Towering 52 meters above the sea, Bengtskär lighthouse is the tallest one in Scandinavia. The building started in in 1905 after the shipwreck of S/S Helsingfors and was completed in 1906. The lighthouse was designed by architect Florentin Granholm. On December a special petrol lantern, designed and built in Paris, was brought to Bengtskär and installed atop the tower.
German fleet bombarded Bengstkär in the First World War in 1914. Since the Gulf of Finland was heavily mined, it was not until 1919 that the surrounding seas were declared safe for shipping, that the light was lit again.
After the war the military value of Bengtskär increased as part of the defence system of independent Finland. In Second World War (1941) Soviet Union made a suprise attack to island. After a bloody battle, the small Finnish garrison emerged victorious. Intermittent repairs to the facility continued during the post-war period.
