this donation was revoked during the Great Reduction and the farms were returned to private ownership. They were later combined into the Lauttasaari manor, whose current main building was commissioned by Claes Wilhelm Gyldén in 1837. The southernmost part of Lauttasaari was taken into the use of the Russian military during the Crimean War. No garrison was founded in Lauttasaari, but fortifications and ammunition depots of the coastal artillery were built on the island. After Finland became independent the areas was owned by the state of Finland, but as the Finnish Defence Forces had no use for the area, in 1927 it was transferred to the city of Helsinki, which founded a folkpark in the area. During the Winter War and the Continuation War an anti-aircraft battery against the bombing of Helsinki was situated on Myllykallio in Lauttasaari. During the Continuation War the battery was armed with six heavy anti-aircraft cannons. One of these cannons was revealed as a memorial monument on Myllykallio on 12 June 1980. The leading battery of the southwestern sector was located in Veijarivuorenniemi in Lauttasaari, of which one cannon has been preserved on site as a memorial monument. Julius Tallberg era and early building plans The pace of the development of Lauttasaari has been set by traffic connections. In the early 20th century the island was only inhabited by farms and villas. In 1911 Julius Tallberg bought the Lauttasaari manor for 750 thousand Finnish markka, whose lands covered about half of the island. Tallberg tried to sell the lands to the city of Helsinki, but as the city did not expect its lands to spread to the island, the deal failed. Tallberg started developing the island by himself and hired Birger Brunila to make a building plan. According to the plan, the island would be mostly built as a villa town, but it took over 20 years before this plan was put to action. Tallberg founded a marine spa and a café named Drumsö Casino on the island. From 1913 to 1917 the island was also served by a horse-drawn tram, trafficking from the ferry pier at the start of the current Lauttasaarentie street to Katajaharjunniemi. According to Eliel Saarinen's 1918 Pro Helsingfors plan a large part of Lauttasaari would be designated as a harbour area, with a train connection from the Leppävaara railway station at the current sites of Ring I and Länsiväylä.
