Karlova Koruna Chateau (Charles's Crown) is one of the most iconic Baroque chateau in the Czech Republic and designed by Jan Santini-Aichel, one of the most influential architects of the baroque period. The chateau was built between 1721 - 1723 as the representative summer seat for Frantisek Ferdinand Count Kinský, and in honor of the coronation of Emperor Charles VI. King of Bohemia; it later took the name “Charles Crown” to commemorate the Emperor’s visit to the castle.
Kost Castle is is a fortified stronghold built after 1349 by Benes of Vartemberk. During the following centuries, Kost was acquired and further expanded by various families: Házmburk, Šelmberk and Biberštejn (who added the "renaissance" wing). Later Kryštof of Lobkowitz added a palace, a brewery and farm buildings, which were fortified and joined to the castle. It was ultimately inherited by Flaminio dal Borgo Netolický in 1874 and later entered into the Kinský dal Borgo family who own it to this day. Kost is located near the town of Jičín, in the famous region called Český ráj (Bohemian Paradise) and is one of the best-preserved gothic castles in Bohemia.
