Charlottenlund Palace is a minor palace near Copenhagen. In its original baroque form it was built between 1731 and 1733 on the foundations of a palace named Gyldenlund. The palace was named after Charlotte Amalie, the daughter of Frederick IV of Denmark and the sister of Christian VI of Denmark. In the 1880s, the palace was extended and rebuilt to reflect the French renaissance style that characterizes its architecture today.
The first royalty moved into the palace in 1869, when Crown Prince Frederick and his wife Lovisa of Sweden moved in. Both Christian X of Denmark and Haakon VII of Norway were born in the palace. The queen dowager Louise lived in the palace until her death in 1926. The royal family discontinued using the palace in 1935 and made it available to the Danish Fishery Survey.
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.
