The Riddarholmen Church (Riddarholmskyrkan) is the burial church of the Swedish monarchs. The congregation was dissolved in 1807 and today the church is used only for burial and commemorative purposes. Swedish monarchs from Gustavus Adolphus (d. 1632 AD) to Gustaf V (d. 1950) are entombed here (with exceptions such as Queen Christina who is buried within St. Peter's Basilica in Rome), as well as the earlier monarchs Magnus III (d. 1290) and Charles VIII (d. 1470).
Riddarholmen church is one of the oldest buildings in Stockholm, parts of it dating to the late 13th century, when it was built as a greyfriars monastery. After the Protestant Reformation, the monastery was closed and the building transformed into a Protestant church. A spire designed by Willem Boy was added during the reign of John III, but it was destroyed by a strike of lightning on July 28, 1835 after which it was replaced with the present cast iron spire.
Coats of arms of knights of the Order of the Seraphim are in the walls of the church. When a knight of the Order dies, his coat of arms is hung in the church and when the funeral takes place the church bells are rung constantly from 12:00 to 13:00.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.
