The St. Mary's Church in Sønderborg is located on a hill and is a very iconic for the city. In the Middle Ages there was a leper colony on a hill just outside the city. It was named after Saint George and around 1300 the chapel of this leper colony stood in the place of the present St. Mary's Church. After the old parish church of the city, the St. Nicholas Church, was demolished around 1530, the Saint-George chapel became the new main church. Towards the end of the 16th century, John II, Duke of Schleswig-Holstein-Sonderburg commissioned the enlargement of the building in order to make it suitable for the function of the parish church of his city.
In 1595 a start was made on the partial demolition of the old church and the construction of the new church. Only parts of the old medieval church remained. From the medieval church, a medieval wooden wall cupboard dating from about 1400 remained. The solemn inauguration of the new parish church took place just before Christmas in 1600. In 1649 the George Church was renamed as the Mary Church.References:
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.
