The undisputed symbol of Montegalda is the ancient castle which dominates the entire plain, one lucky survivor of the three manors, two of which stood in Montegaldella and Cervarese S. Croce. The building changed over the years and in the 18th century it was transformed from a military facility into a Venetian villa. Its foundation dates back probably to 1176 but in the courtyard a foundation of the Roman period was found, which anticipates that construction. The castle is undoubtedly impressive, marked by three towers, a keep and the crenellated ring-shaped walls of the Guelph form, which would host the famous 'trabocchetto' (trap door) to thwart the invaders. After the tyrant Ezzelino da Romano in 1300, the domain of the castle passed to the dominion of the Scala family of Verona and later, in 18th century it was transformed into a Venetian villa. The castle of Montegalda now seems to have regained its former glory thanks to a meticulous restoration, reflecting the still incredible charm and mystery.
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.
