Kirkkosaari ("The Church Island", also known as Köyliönsaari) is one of the oldest places of residence in Satakunta area. Two Iron Age cemeteries are located at the north side of Kirkkosaari.
According the legend Lalli, the pagan chief of Kirkkosaari manor, killed bishop Henry on the ice of lake Köyliönjärvi on January 20, 1156. Although Henry has never been officially canonized, he has been referred to as a saint since as early as 1296 according to a papal document of the time. After this the manor and island was moved as the property of Turku bishop. Since 1746 the manor has been owned by Cedercreutz family and is still in private use. Present buildings are from the 18th and 19th centuries.
The church of Köyliö has been in Kirkkosaari since the Middle Ages. The present wooden church was built in 1752 to the old cemetery site. There are also some remains of the medieval chapel in Kirkkosaari manor garden.
The Seaplane Harbour is the newest and one of the most exciting museums in Tallinn. It tells stories about the Estonian maritime and military history. The museum’s display, that comprises of more than a couple of hundred large exhibits, revitalizes the colourful history of Estonia.
British built submarine Lembit weighing 600 tones is the centrepiece of the new museum. Built in 1936 for the Estonian navy, Lembit served in the World War II under the Soviet flag. It remained in service for 75 years being the oldest submarine in the World still in use until it was hauled ashore in 2011. Despite its long history, Lembit is still in an excellent condition offering a glimpse of the 1930s art of technology.
Another exciting attraction is a full-scale replica of Short Type 184, a British pre-World War II seaplane, which was also used by the Estonian armed forces. Short Type 184 has earned its place in military history by being the first aircraft ever to attack an enemy’s ship with an air-launched torpedo. Since none of the original seaplanes have survived, the replica in Seaplane Harbour is the only full-size representation of the aircraft in the whole World.
Simulators mimicking a flight above Tallinn, around-the-world journey in the yellow submarine, navigating on the Tallinn bay make this museum heaven for kids or adventurous adults.
Seaplane Harbour operates in architecturally unique hangars built almost a century ago, in 1916 and 1917, as a part of Peter the Great sea fortress. These hangars are the World’s first reinforced concrete shell structures of such a great size. Charles Lindbergh, the man who performed the first solo flight across the Atlantic Ocean, landed here in 1930s.
On the outdoor area visitors can tour a collection of historic ships, including the Suur Tõll, Europe's largest steam-powered icebreaker.
