Mauerbach Charterhouse is a former Carthusian monastery. Founded in 1314 by the Austrian duke Frederick the Fair and rebuilt in the 17th and 18th centuries, the Baroque monastic complex is one of the most important structures of its kind in Austria.
The monastery was plundered and set on fire by Ottoman troops during the 1529 Siege of Vienna and suffered further serious structural damage by the 1590 Neulengbach earthquake. Under Abbot Georg Fasel (1616-1631) an intensive rebuilding programme began, finishing in 1660, during which the great majority of the present-day buildings were constructed. The chronicle of the charterhouse written by Abbot Leopold Brenner was available from as early as 1669, but was not printed until 1725. Brenner had lived here from 1641 and made his profession in 1650, and was thus an eye witness of the building of the early Baroque monastery. In 1683 renewed Turkish assaults during the Battle of Vienna caused more destruction, launching a further programme of repairs and refurbishment s which finished only in 1750.
In 1782 the monastery was dissolved as 'non-productive' by Emperor Joseph II during his rationalist reforms and from 1786 the premises were used for the care of the old and incurably ill of the city of Vienna. Many structural alterations were carried out to adapt the buildings to their new function.
In 1944-45 the former monastery was put to use as an emergency hospital. Between 1945 and 1961 the charterhouse was used to house homeless people. During this period the structure was badly neglected, and allowed to fall derelict from exposure to the elements. Since 1984 the complex has housed the workshops of the Bundesdenkmalamt (Monuments Office).

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.
