The Čachtice castle ruins stands on a hill featuring rare plants, and has been declared a national nature reserve for this reason. The castle was a residence and later the prison of the Countess Elizabeth Báthory, who is alleged to have been the world's most prolific female serial killer.
Čachtice was built in the mid-13th century by Kazimir from the Hont-Pázmány gens as a sentry on the road to Moravia. Later, it belonged to Máté Csák, the Stibor family, and then to the famous Bloody Lady Elizabeth Báthory. Čachtice, its surrounding lands and villages, was a wedding gift from the Nádasdy family upon Elizabeth's marriage to Ferenc Nádasdy in 1575.
Originally, Čachtice was a Romanesque castle with an interesting horseshoe shaped residence tower. It was turned into a Gothic castle later and its size was increased in the 15th and 16th centuries. A Renaissance renovation followed in the 17th century. Finally, in 1708 the castle was captured and plundered by the rebels of Ferenc II Rákoci (Francis II Rákóczi). It has been in decay since.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.
