The Bishop's Palace, Kirkwall was built at the same time as the adjacent St Magnus Cathedral. It was built for the cathedral's first bishop, William the Old of the Norwegian Catholic church who took his authority from the Archbishop of Nidaros (Trondheim). The ruined structure now looks like a small castle.
Originally it is thought to have been like a typical Royal Norwegian Palace, with a large rectangular hall above store rooms and a tower house as the Bishop's private residence. King Haakon IV of Norway, overwintering after the Battle of Largs, died here in 1263, marking the end of Norse rule over the Outer Hebrides. The neglected palace had fallen into ruins by 1320.
In 1468 Orkney and Shetland were pledged by Christian I of Denmark and Norway for the payment of the dowry of his daughter Margaret, betrothed to James III of Scotland, and as the money has never since been paid, their connection with the crown of Scotland has been perpetual. In 1526 the palace came briefly into the possession of William, Lord Sinclair, before he was ordered to return it to the Bishop of Orkney. When King James V of Scotland visited Kirkwall in 1540 he garrisoned his troops in the Palace and in Kirkwall Castle. Soon afterwards' extensive restoration was begun by Bishop Robert Reid, the last and greatest of Orkney's medieval Bishops who also founded the University of Edinburgh. Reid added a round tower, the Moosie Toor.
Ownership passed to Robert Stewart, 1st Earl of Orkney, in 1568, then to his son Patrick Stewart, 2nd Earl of Orkney who planned to incorporate it into his Earl's Palace, Kirkwall, but debts forced him to return it to Bishop James Law. Earl Patrick's son Robert seized both palaces in 1614, and a siege followed, though it is not known if this caused damage to the structures, both of which are now ruins.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.
