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.

Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
