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:
First record of Kastelholma (or Kastelholm) castle is from the year 1388 in the contract of Queen Margaret I of Denmark, where a large portion of the inheritance of Bo Jonsson Grip was given to the queen. The heyday of the castle was in the 15th and 16th centuries when it was administrated by Danish and Swedish kings and stewards of the realms. Kastelhoma was expanded and enhanced several times.
In the end of 16th century castle was owned by the previous queen Catherine Jagellon (Stenbock), an enemy of the King of Sweden Eric XIV. King Eric conquered Kastelholma in 1599 and all defending officers were taken to Turku and executed. The castle was damaged under the siege and it took 30 years to renovate it.
In 1634 Åland was joined with the County of Åbo and Björneborg and Kastelholma lost its administrative status.
