Duchcov palace houses a museum with a collection of historic furniture. Also on display is the painting and portrait gallery of the Waldsteins, including portraits of the most famous member of this family, Albrecht von Wallenstein, Duke of Friedland, by Anthony van Dyck. One room is dedicated to Giacomo Casanova, who was employed here as a librarian from 1785 to 1798, and his memoirs were written here in the years before his death in 1798.
The château was founded as a fort in the 13th century by the Hrabišic family, which resided at the Osek Castle. Not earlier than 1527, the Lobkowicz family replaced the fort with a one-wing Renaissance palace. Marie Polyxena of Thalmberg, the widow of František Josef of Lobkowicz, married secondly Maximillian, Count of Waldstein in 1642. Their son Jan Bedřich, Count of Waldstein, later the Archbishop of Prague, was apprised with the French architect and painter Jean Baptiste Mathey, and he brought him to Duchcov for the purpose of rebuilding the residence. The château was incorporated in the Waldstein's family fideicommis and passed on through inheritance to Ernst Joseph Count Waldstein and to his descendants until it was nationalised in 1945.
Mathey designed a huge Baroque complex, including a large park and a hospital. The decoration of the building was provided by the best Baroque artists in Bohemia, like the sculptors Matyáš Bernard Braun, Ferdinand Maxmilián Brokoff, and painter Václav Vavřinec Reiner. Between 1785 and 1798, Giacomo Casanova, the so-called secretary of the 18th century, spent the last thirteen years of his amazing life in Duchcov.
In the 19th century, the château was rebuilt in the classicist style and the garden in the romantic style. The Waldstein family left the place in 1921. At present, the château is state-owned and open to visitors.
References:Towering 52 meters above the sea, Bengtskär lighthouse is the tallest one in Scandinavia. The building started in in 1905 after the shipwreck of S/S Helsingfors and was completed in 1906. The lighthouse was designed by architect Florentin Granholm. On December a special petrol lantern, designed and built in Paris, was brought to Bengtskär and installed atop the tower.
German fleet bombarded Bengstkär in the First World War in 1914. Since the Gulf of Finland was heavily mined, it was not until 1919 that the surrounding seas were declared safe for shipping, that the light was lit again.
After the war the military value of Bengtskär increased as part of the defence system of independent Finland. In Second World War (1941) Soviet Union made a suprise attack to island. After a bloody battle, the small Finnish garrison emerged victorious. Intermittent repairs to the facility continued during the post-war period.
