St. Hedwig's Cathedral is the seat of the archbishop of Berlin. It was built in the 18th century as the first Catholic church in Prussia after the Protestant Reformation by permission of King Frederick II. The intention of Frederick was to offer the numerous Catholic immigrants who had arrived in Berlin, especially those from Upper Silesia, a place of worship. The church was therefore dedicated to the patron of Silesia and Brandenburg, Saint Hedwig of Andechs. The building was designed by Georg Wenzeslaus von Knobelsdorff modeled after the Pantheon in Rome and construction started in 1747, interrupted and delayed several times due to economic problems. It was not opened until November 1, 1773 when the king's friend, Ignacy Krasicki, then Bishop of Warmia (later Archbishop of Gniezno), officiated at the cathedral's consecration.
After the Kristallnacht pogroms that took place over the night of 9–10 November 1938, Bernhard Lichtenberg, a canon of the cathedral chapter of St Hedwig since 1931, prayed publicly for Jews in the evening prayer following. Lichtenberg was later jailed by the Nazis and died on the way to the concentration camp at Dachau. In 1965 Lichtenberg's remains were transferred to the crypt at St. Hedwig's.
The cathedral burned down completely in 1943 during air raids on Berlin and was reconstructed from 1952 up to 1963.
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.
