Trakai Peninsula Castle is one of the castles in Trakai. Built around 1350–1377 by Kęstutis, Duke of Trakai, it was an important defensive structure protecting Trakai and Vilnius, capital of the Grand Duchy of Lithuania, against attacks of the Teutonic Knights. Much of the castle was destroyed in the 17th century. Remaining walls and towers are preserved and protected by the Trakai Historical National Park.
The castle had seven towers connected by a 10 m high wall. The three largest towers, measuring 15 m × 15 m, protected the most vulnerable southwestern flank. A 12–14 m wide moat separated the structure from the town. The castle was attacked in 1382 and 1383 (during the civil war of 1381–1384) and in 1390 (during the civil war of 1389–1392). After the 1422 Treaty of Melno, the castle lost its significance as a defensive structure. It is known that Grand Dukes used it as a residence. Sigismund Kęstutaitis was murdered in the castle on 20 March 1440.
In the 16th century the castle was used as a prison. It was destroyed during the Russo-Polish War (1654–1667) and never rebuilt. The territory was granted to a Dominican cloister in 1678 by Marcjan Aleksander Ogiński, Voivode of Trakai. It was not until the 1770s that the monks eventually built their monastery and church; these buildings are also part of the castle ensemble.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.
