Fort Thüngen is a historic fortification in Luxembourg City sited in Dräi Eechelen Park. Named after the Austrian commander-in-chief of the fortress, Baron of Thüngen, it was built in 1732 to enclose the defence work called Redoute du Parc (Park Redoubt) set up by Vauban 50 years before. A deep moat surrounded Fort Thüngen which was accessible only through a 169-metre long underground tunnel through the rocks from Obergrünewald. In 1836 the Prussians extended the Fort and in 1860 strengthened it again.
Most of the original fortress was demolished after the 1867 Treaty of London, which demanded the demolition of Luxembourg City's numerous fortifications. The three towers and the foundations of the rest of the fort were all that remained. During the 1990s, the site was reconstructed in its entirety, in parallel with the development of the site for the construction of the Mudam, Luxembourg's museum of modern art.

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.
