The Castello Visconteo di Pagazzano is a moated, late-medieval castle which originates from the 11th century. It was burned down and 200 inhabitants were killed in a battle in 1353. The castle and the territory of Gera d’Adda, including Pagazzano, was inherited in 1354 by Bernabò Visconti. The territory was disputed over the centuries by surrounding ruling forces, and various Visconti descendants. In the 19th century, the castle was owned by the Crivelli family until 1968 when it was bought by a private initiative, and sold to the Comune di Pagazzano in the year 2000.
The structure has been built with bricks and is rectangular in shape. The southern part has lost the towers at the south-east and south-west corners. In 1553 Galeazzo Visconti ordered the integration of the mansion into the castle. The drawbridge still exists and is used as pedestrian passage, the castle is also surrounded by a moat full of water. The drawbridge is on the northern side and is about 4 metres long, it still works today. The main entrance is also here, situated in the majestic central tower. The defensive use of this central tower depended on a system of battlements. Along the walls there is a look out tower where a bell rang, so the people could take refuge inside the walls in case of danger. The oldest part includes huge rooms and the dungeons.
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.
