The Lighthouse of Genoa (Lanterna di Genova) serves as a symbol and a landmark for Genoa. Built of masonry, at 76 m it is the world's fifth tallest lighthouse and the second tallest 'traditional' one. Between 1543 and the construction of the lighthouse on Île Vierge, France in 1902, it was the tallest lighthouse in the world. When measured as a whole with the natural rock on which it stands, as it is commonly perceived and represented, its height is 117 m, which would make it the second tallest lighthouse in the world, the tallest in Europe, and the tallest traditional lighthouse.
It is constructed in two square portions, each one capped by a terrace; the whole structure is crowned by a lantern from which the light is shone.
The tower was shelled during the bombardment of Genoa by the French in 1684; the windows which were damaged were replaced on the orders of Louis XIV in 1692. In 1778 construction began on a new lighting system designed to counteract damage done to the lighting apparatus over several centuries of use. In 1840 a rotating Fresnel lens was installed; the system was formally inaugurated in January 1841. It was modified up until the end of the century in order to increase its capability; the entire lighthouse was modernised again in 1913, but the electrification was poorly done, and had to be refitted in 1936. One last major restoration project, begun after American and British air attacks of World War II, was completed in 1956. It is also the symbol surrounding the Derby della Lanterna between two football clubs, Genoa C.F.C. and U.C. Sampdoria.
Adjacent to the tower is the Museo della Lanterna. The museum mainly covers the history of the city and the port, and contains a good deal of archival material. Some of the displays also cover the history of navigation and navigational aids in Genoa, and describe various signaling systems that have been used at sea. Part of a Fresnel lens, similar to that found in the lighthouse itself, is shown in such a manner as to display its inner workings. In addition to the permanent displays, temporary exhibits are also sometimes shown at the museum.
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.
