Vadstena Castle was originally built by King Gustav I in 1545 as a fortress to protect Stockholm from enemies from the south. The fortress consisted of three smaller stone buildings facing the lake, Vättern, three 31 meter wide ramparts, a courtyard, a moat and four circular cannons turrets. The original ramparts were torn down in the 19th century and the present ramparts were inaugurated in 1999. The stone buildings later formed the ground floor of the castle.
On August 22, 1552, King Gustav I married his third wife, Catherine Stenbock, in Vadstena. One of the castle banqueting halls is called The Wedding Hall, although its construction wasn't finished in time for the wedding. The reconstruction from fortress into a castle began in the 1550s, when prince Magnus became Duke of Östergötland. Duke Magnus had a mental illness and was the only son of Gustav I who didn't become king of Sweden. Magnus died in 1595 and is buried in the nearby Abbey Church.
In 1620 the castle construction was completed and all the kings of the House of Vasa up till then had led the construction. Since 1620, the castle has been very well preserved, and is one of Sweden's best examples of Renaissance architecture. Vadstena Castle was a royal palace until 1716, when the royal family lost interest in it; after which it became a storage for grain.
Since 1899, the castle has housed the Provincial Archives and today visitors can also find a Castle Museum with 16th and 17th century furniture, portraits and paintings. During summers the courtyard plays host to many concerts; both classical and pop music.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.
