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:Considered to be one of the most imposing Roman ruins, Diocletian’s palace is certainly the main attraction of the city of Split. The ruins of palace, built between the late 3rd and the early 4th centuries A.D., can be found throughout the city. Today the remains of the palace are part of the historic core of Split, which in 1979 was listed by UNESCO as a World Heritage Site.
While it is referred to as a 'palace' because of its intended use as the retirement residence of Diocletian, the term can be misleading as the structure is massive and more resembles a large fortress: about half of it was for Diocletian's personal use, and the rest housed the military garrison.
Architecture
The palace has a form of an irregular rectangle with numerous towers on the western, northern, and eastern facades.
