The octagonal Place de la Concorde is the largest square in Paris. It is situated between the Tuileries and the Champs-Elysées. In 1763, a large statue of king Louis XV was erected at this site to celebrate the recovery of the king after a serious illness. The square surrounding the statue was created later, in 1772, by the architect Jacques-Ange Gabriel. It was known as the place Louis XV.
In 1792, during the French revolution, the statue was replaced by a another, large statue, called Liberté (freedom) and the square was called Place de la Révolution. A guillotine was installed at the center of the square and in a time span of only a couple of years, 1119 people were beheaded here. Amongst them many famous people like King Louis XVI, Marie-Antionette, and Obelisk at Place de la Concorde, Paris revolutionary Robespierre, just to name a few. After the revolution the square was renamed several times until 1830, when it was given the current name Place de la Concorde.
In the 19th century the 3200 years old obelisk from the temple of Ramses II at Thebes was installed at the center of the Place de la Concorde. It is a 23 meters tall monolith in pink granite and weighs approximately 230 tons. In 1831, it was offered by the Viceroy of Egypt to Louis Philippe. The obelisk is covered with hieroglyphs picturing the reign of pharaohs Ramses II & Ramses III. Pictures on the pedestal describe the transportation to Paris and its installation at the square in 1836.
At each corner of the octagonal square is a statue representing a French city: Bordeaux, Brest, Lille, Lyon, Marseille, Nantes, Rouen and Strasbourg. They were installed in 1836 by Jacob Ignaz Hittorf, who redesigned the Place de la Concorde between 1833 and 1846. That same year a bronze fountain, called La fontaine des Mers was added to the square. A second one, the Elevation of the Maritime fountain, was installed in 1839. Both fountains were designed by Hittorf.
References:The Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
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.
