St. Nicholas Church (Greifswalder Dom St. Nikolai) is a Brick Gothic church located in the western part of the centre of Greifswald. The first written sources referring to a church dedicated to St. Nicholas in Greifswald are from 1263. The oldest extant parts of the church have been dated to the last third of the 13th century. In 1385 work was begun on a new choir with a straight eastern wall, which was finished in 1395.
In connection to the founding of the University of Greifswald, the church was raised to the status of collegiate church. The new status of the church also brought wealth, and in the same year construction began to make the tower higher. In the years 1480–1500, the octagonal upper part of the tower was built and with the addition of the also octagonal, c. 60 metres high Gothic spire at the beginning of the 16th century, the construction of the tower was finished. At the time, it reached a height of 120 metres.
The church lost its spire twice during severe storms. The first time was in 1515, when the top collapsed, apparently without causing any severe damage to the church building. It was not replaced until 1609. The collapse on 13 February 1650 initially destroyed the roof of the church, causing several of the vaults of the nave and southern aisle to collapse, and a few days later, the eastern wall of the church also collapsed. The interior furnishings of the church were completely destroyed. Immediately after the collapse, the council of the city called for donations for the reconstruction of the church. In 1651 the vaults and roof were rebuilt, and one year later the church tower received its new, Baroque spire.
The interior of the church was thoroughly renewed in 1823–1832.
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.
