In 878 the East Frankish king Carloman of Bavaria dedicated the Treffen estates around Lake Ossiach to the Benedictine monastery of Ötting. In the late 10th century the lands passed to the Bishops of Passau and later to Emperor Henry II, who conferred them to a certain Count Ozi, affiliated with the Styrian Otakar dynasty and father of Patriarch Poppo of Aquileia.
A church probably already existed at Ossiach, when Count Ozi about 1024 established the Benedictine abbey, the first in the medieval Duchy of Carinthia. The first monks probably descended from Niederaltaich Abbey in Bavaria. Ozi's son Poppo succeeded in removing the proprietary monastery from the influence of the Salzburg archbishops and to affiliate it with the Patriarchate of Aquileia, confirmed by Emperor Conrad II in 1028. Upon the extinction of the Styrian Otakars in 1192, the Vogtei of Ossiach according to the Georgenberg Pact passed to the Austrian House of Babenberg. In 1282 it finally fell to the Habsburgs.
The Romanesque church itself was first mentioned in 1215, built on the groundplan of a basilica, with the tower above the crossing. Restored in a Late Gothic style after a fire in 1484, the abbey, a member of the Benedictine Salzburg Congregation from 1641, was extensively altered in the Baroque period, including stucco decoration of the Wessobrunner School.
Ossiach Abbey was dissolved by order of Emperor Joseph II in 1783, after which the buildings were used as a barracks. In 1816 the premises were largely demolished. Between 1872 and 1915 the few remaining buildings were again used as a barracks and as stabling. Since 1995 the premises have been owned by the administration of Carinthia. The church since the dissolution has served the local parish. Two stained glass windows were donated by Karl May in 1905, though according to recent research the popular writer had probably never visited Ossiach.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.
