While the site of the Dudelange castle ruins bears traces of Gallo-Roman structures, the first evidence of a castle in the area is in Dudelange itself where a castle belonging to the Lords of Gymnich was destroyed around 1400 by Robert de Bar. At the beginning of the 15th century, work began on building a fortified castle which was completed early in the 16th century with Gothic and Renaissance influences. The finely cut stones and sculptures show how much the lords of Gynmich, Boulay, Neufchâtel, Hunolstein and Isembourg invested in their luxurious fortress. However from 1542 the castle was taken and retaken when Francis I and Henry II of France were at war with Emperor Charles V. In 1552, the castle was destroyed and deprived of any strategic value. Thereafter the ruins were used as a quarry for the surrounding villages.
Since the 1970s, the Amis de l’Histoire de Dudelange et du Mont Saint-Jean (Friends of the History of Dudelange and Mont St. Jean) have explored the ruins, discovering the foundations of several towers, the palace, living quarters, stables and outhouses. Three wells and a reservoir were partly unearthed. The ditches and the entrance to the castle can still be seen.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.
