During the Middle Ages, Wil Castle was built near the village and it became the seat of the Herrschaft of Schlosswil. The lords of the fort, the Freiherren von Wiler, were first mentioned in 1146. The von Wiler family died out around 1300, and the village and associated territory passed through several noble families, including the Freiherren von Signau and eventually the Senn von Münsingen family. The territory was split in half and passed through several Bernese patrician families until Burkhard von Erlach reunited the two halves in 1514.
In 1546 the medieval castle was destroyed in a fire. Shortly thereafter it was rebuilt as a larger castle under the direction of the master builder Niklaus von Wattenwyl-May. The current appearance comes from a 1780 renovation that gave the castle a Baroque exterior.
Following the 1798 French invasion, under the Helvetic Republic the nobility lost much of their power and property and by 1812 the castle was acquired by the Canton of Bern. In 1818 the castle tower became the only granary for the district of Konolfingen. A famine in 1816-17 was partly alleviated by the grain at the castle. In 1847 the tower was converted into a prison, a role that it filled until 1881. Even after the prison closed, the castle continued to be used by the district administration and courts. In 2010 the District of Konolfingen was dissolved and the need for district offices vanished. In 2011 it was acquired by Matthias Steinmann, who founded the Steinmann Foundation to operate the castle.
The original fortress tower was built in first half of the 12th century for the von Wiler family. The walls of the square tower are 38 meters tall and to the peak of the roof is 43.5 meters.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.
