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:Krickenbeck moated castle is one of the oldest on the lower Rhine. Its history dates back to the year 1104, when the castle was first mentioned. It is unclear why the old castle, which was certainly inhabited by Count Reginar, was abandoned or destroyed. In the mid-13th century the castle was moved to the current location. At the end of the 14th century the new castle belonged to the Counts of Kleve.
Johann Friedrich II of Schesaberg converted the castle into a Baroque mansion between 1708-1721. On September 7, 1902, a fire destroyed the entire mansion. From 1903 to 1904, a three-winged castle was built in the Neo-Renaissance style. Today Krickenbeck is a conference center.
