Zwiefalten Abbey was a Benedictine monastery founded in 1089 at the time of the Investiture Controversy by Counts Gero and Kuno of Achalm, advised by Bishop Adalbero of Würzburg and Abbot William of Hirsau. The first monks were also from Hirsau Abbey, home of the Hirsau Reforms (under the influence of the Cluniac reforms), which strongly influenced the new foundation. Noker von Zwiefalten was the first abbot and led from 1065–90.
During the 12th century Saint Ernest (died 1148) was abbot. Between 1145 and 1149 he participated in the Second Crusade to regain the Holy Lands including Jerusalem.
Although Pope Urban VI granted special privileges to it, Zwiefalten Abbey was nevertheless the private monastery of the Counts of Achalm, later succeeded by the Counts of Württemberg. The abbey was plundered in 1525 during the German Peasants' War. Christoph Rassler was abbot from 1658–75 and Augustin Stegmüller was abbot in the 18th century.
In 1750 the abbey was granted the status of Reichsabtei, which meant that it had the status of an independent power subject only to the Imperial Crown and was free of the rule of Württemberg. On 25 November 1802, however, it was secularised and dissolved and became a lunatic asylum and later psychiatric hospital, which it is today, as well as the site of the Württemberg Psychiatry Museum.
The present buildings were constructed in German Baroque style from 1739–47 under the direction of Johann Michael Fischer (1692–1766) of Munich, who began overseeing the work in 1741. The interior, considered a model of Baroque design, is filled with ornate chapels and gilded balustrades, dominated by the high altar, which combines a Gothic statue of the Virgin Mary dating from 1430 with Baroque additions (dating from about 1750) by Johann Joseph Christian (1706–77). The elaborate frescoes are by Franz Joseph Spiegler (1691–1757).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.
