By the early 1300s, Gostynin emerged as an important administrative center of Mazovia. In 1329, it became the seat of a castellan. In 1352, Siemowit III for the first time used the title “Duke of Gostynin”. It was probably during his reign that a defensive castle with a tower was built. Siemowit IV expanded the castle, making it his favorite residence. W³adys³aw II Jagie³³o visited Gostynin twice (1414, 1419). Siemowit IV died here in 1426, and after his death, the complex was rebuilt, with a wooden chapel added to it in 1439.
In 1612, Russian Tsar Vasili IV died at the Gostynin castle, in which he had been kept with two brothers since 1611. In 1793, following the second partition of Poland, Gostynin was captured by Prussian army. The castle, which had for long time been neglected, was pulled down, and its archive was seized by the occupiers. In 1824, the government of Russian-controlled Congress Poland invited to Gostynin 124 German cloth makers, who came with their families. The town began the process of recovery: St. Martin church, town hall and inn were rebuilt, and ruins of the castle were turned into a Protestant church.References:
Hluboká Castle (Schloss Frauenberg) is considered one of the most beautiful castles in the Czech Republic. In the second half of the 13th century, a Gothic castle was built at the site. During its history, the castle was rebuilt several times. It was first expanded during the Renaissance period, then rebuilt into a Baroque castle at the order of Adam Franz von Schwarzenberg in the beginning of the 18th century. It reached its current appearance during the 19th century, when Johann Adolf II von Schwarzenberg ordered the reconstruction of the castle in the romantic style of England's Windsor Castle.
The Schwarzenbergs lived in Hluboká until the end of 1939, when the last owner (Adolph Schwarzenberg) emigrated overseas to escape from the Nazis. The Schwarzenbergs lost all of their Czech property through a special legislative Act, the Lex Schwarzenberg, in 1947.
The original royal castle of Přemysl Otakar II from the second half of the 13th century was rebuilt at the end of the 16th century by the Lords of Hradec. It received its present appearance under Count Jan Adam of Schwarzenberg. According to the English Windsor example, architects Franz Beer and F. Deworetzky built a Romantic Neo-Gothic chateau, surrounded by a 1.9 square kilometres English park here in the years 1841 to 1871. In 1940, the castle was seized from the last owner, Adolph Schwarzenberg by the Gestapo and confiscated by the government of Czechoslovakia after the end of World War II. The castle is open to public. There is a winter garden and riding-hall where the Southern Bohemian gallery exhibitions have been housed since 1956.
