It is believed that the Lužnica manor was built at the beginning of the 18th century. Since 1791 the estate was the owned by Rauch noble family. They soon had the manor renovated and further expanded. At the end of 19th century, Marija Jurić Zagorka, lived in the manor from the age of 3 until 10 years, as her father was estate manager for the Rauch family. She later became one of the most prominent Croatian writers of a time. Countess Antonija noticed the talent of young Zagorka, so she made possible for her to use the castle library and attend private schooling lessons along her own kids. In 1923, Geza, the final member of Rauch family was killed under suspicious circumstances. Following his death, his widow Antonija, sold Lužnica, which then became property of Daughters of Charity of Saint Vincent de Paul.
At a time, this order was looking for a large estate close to capital, Zagreb, for sixty of its members. One part of the manor was soon turned into a hospital, another part into a chapel, while surrounding land was used for agriculture. The goods from the estate were shipped to a Sisters of Charity Hospital in Zagreb. At the beginning of the 20th century, the manor was also used as a kindergarten, music and householdng school for the local community.
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.
