The city of Gizycko (Ger. Lötzen) was founded as a village surrounding the Teutonic Order's castle, built around 1340. The castle was built during the reign of Grand Master Winrich von Kniprode, located in a strategic position - on the isthmus between Lakes Niegocin and Kisajno. It was a dwelling with a rectangular courtyard, surrounded by a wall, and functioned as a residence of the Teutonic Order's prosecutor. The castle was destroyed during the attacks of Lithuanians led by Prince Kiejstut, but was rebuilt by the Teutonic Knights soon after. The Thirteen Years' War caused much damage to both the castle and the settlement. After the secularisation in 1525, the castle became the princely administrator's seat and was reconstructed in Renaissance style, during 1613-1614.
In the 17th century the castle became private property. The new owner added two wings (destroyed by fire in the same century) for administrative purposes, and a building with a small cylindrical tower, which was destroyed in 1945. In the 19th century, part of the castle was pulled down, and only one four-storey dwelling wing with a saddle roof and a cellar with cruciform vault were left. The castle has remained in this form until today. It hosted, among others, general Dabrowski and his officers in 1807. It was temporarily used to house the builders of the Gizycki Canal, and served also as the Fortress Boyen Commandant's quarters. Today the remnants of the castle are in bad condition and are not being restored.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.
