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:Kakesbeck is one of the largest medieval fortifications in Münsterland and the oldest castle in Lüdinghausen. The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
