Långe Jan ("Tall John") is a Swedish lighthouse located at the south cape of Öland. It is one of Sweden's most famous lighthouses and also the tallest lighthouse in Sweden. The lighthouse was built in 1785, probably by Russian prisoner of wars. The tower was built by stone from an old chapel. Originally the light was an open fire, and the tower was unpainted. It was painted white in 1845, and the same year the tower's lantern was installed, to store a colza oil lamp. A couple of years later a black band was added to the tower.
The lighthouse remains in use and is remote-controlled by the Swedish Maritime Administration in Norrköping. During the summer-season it is possible to climb the tower, for a small fee. The buildings surrounding the tower is Ottenby birding station.
References:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
