Kynžvart Castle is a neoclassical palace. After extensive renovations, the castle was reopened to the public in 2000. A guided tour takes visitors through 25 rooms of the castle.
The first castle, built before 1600, collapsed. After the Battle of White Mountain during the Thirty Years' War, the remains of the castle were confiscated and by 1630 granted to the Metternich family. From 1682 to 1691, Count Philipp Emmerich von Metternich turned the decayed ruins into a Baroque residence. From 1821 to 1836, the Austrian Chancellor Klemens Wenzel von Metternich remodeled the building in the neoclassical style with the help of architect Pietro Nobile.
The castle was confiscated from the Metternich family in 1945 by the Czechoslovak government.
The castle has a library that includes over 200 examples of incunabula, medieval manuscripts, valuable prints, scientific books, and scientific encyclopedias. In 1828, a museum was founded to display the castle's natural science collections, coins, historical and technological curiosities, manuscripts, ancient Egyptian monuments, marble sculptures, and pieces of Oriental art.
References:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
